How does oxygen gain electrons in the water molecule?
In the covalent bond between oxygen and hydrogen, the oxygen atom attracts electrons a bit more strongly than the hydrogen atoms. The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.
How does the size of oxygen nucleus?
The nucleus of an oxygen atom has a radius of roughly 3.15 x 10-12 mm.
Why does water have an uneven distribution of electrons?
The water molecule is a polar molecule, meaning that there is an uneven distribution of electron density. Water has a partial negative charge near the oxygen atom due the unshared pairs of electrons, and partial positive charges near the hydrogen atoms.
Why does the oxygen atom go in the middle in the h2o molecule?
Oxygen is electronegative Atoms of oxygen are electronegative and attract the shared electrons in their covalent bonds. Consequently the electrons in the water molecule spend slightly more time around the oxygen atomic center and less time around the hydrogen atomic centers.
How does the molecular structure of a water molecule affect its polarity?
When the two hydrogen atoms bond with the oxygen, they attach to the top of the molecule rather like Mickey Mouse ears. This molecular structure gives the water molecule polarity, or a lopsided electrical charge that attracts other atoms. The end of the molecule with the two hydrogen atoms is positively charged.
How does the shape of the water molecule affect its properties?
The angle between bonds in water is 104.5° making water a bent molecule. The shapes of molecules have important implications. One is that even though both C=O. bonds and O-H bonds have dipoles, carbon dioxide molecules are non-polar due to their linear shape and water molecules are polar due to their bent shape.
How does the size of the nucleus relate to the size of the atom?
The nucleus of an atom is about 10-15 m in size; this means it is about 10-5 (or 1/100,000) of the size of the whole atom. A good comparison of the nucleus to the atom is like a pea in the middle of a racetrack. (10-15 m is typical for the smaller nuclei; larger ones go up to about 10 times that.)
How does the size of the nucleus of an atom compare with that of its electron cloud?
An atomic nucleus is much, much smaller than an atom. The cloud of electrons that "orbit" the nucleus and define the "size" of an atom is roughly 100,000 times as large as that atom's nucleus!
Why does A water molecule have an uneven distribution of charge quizlet?
because there is an uneven distribution of electrons between the oxygen and hydrogen atoms.
How does the molecular structure of A water molecule affect its polarity?
When the two hydrogen atoms bond with the oxygen, they attach to the top of the molecule rather like Mickey Mouse ears. This molecular structure gives the water molecule polarity, or a lopsided electrical charge that attracts other atoms. The end of the molecule with the two hydrogen atoms is positively charged.
How is the bonding in O2 different from that in H2O?
The difference is due to the fact that one water molecule has two hydrogen atoms to one oxygen atom, as explained above. This means it takes two water molecules (2 H2O) to make one oxygen molecule (O2).
How does the molecular structure of water affect its polarity quizlet?
How does the molecular structure of a water molecule affect its polarity? The oxygen has a partial negative charge and the hydrogens have a partial positive charge, yielding a weakly polar water molecule that can form hydrogen bonds.
How does the molecular shape affect polarity?

How does the molecular structure of A water molecule affect its polarity quizlet?
How does the molecular structure of a water molecule affect its polarity? The oxygen has a partial negative charge and the hydrogens have a partial positive charge, yielding a weakly polar water molecule that can form hydrogen bonds.
Why is the size of the nucleus is very small as compared to the size of the atom?
Since the repulsive force acting here is Coulomb repulsion, there is no contact. This means that the size of the nucleus is smaller than 4×10-14m.
How does the size of the nucleus of an atom compare with the size of an atom?
The nucleus of an atom is about 10-15 m in size; this means it is about 10-5 (or 1/100,000) of the size of the whole atom. A good comparison of the nucleus to the atom is like a pea in the middle of a racetrack. (10-15 m is typical for the smaller nuclei; larger ones go up to about 10 times that.)
How does the size of a nucleus depends on its mass number?
The radius size R of nucleus is related to its mass number A asR = R0A1/3 where R0 = 1.1 × 10–15 mIf m is the average mass of a nucleon then mass of nucleus = mA where A is mass number Volume of nucleus∴ Density of nucleus Clearly nuclear density ρN is independent of mass number A.
What causes an uneven charge distribution in a molecule?
A polar covalent bond is a covalent bond in which the atoms have an unequal attraction for electrons and so the sharing is unequal. In a polar covalent bond, sometimes simply called a polar bond, the distribution of electrons around the molecule is no longer symmetrical.
What is uneven distribution of charge on a water molecule called?
Water is a good solvent because of it's polarity. Polarity is an uneven distribution of charge across a molecule. Since there are two Hydrogen atoms, which are positive, and only one oxygen atom, which is negative, the bond becomes polar.
What type of bond between water molecules pulls them into this tight ball?
It is the hydrogen bond that pulls water molecules together which results into a cohesive force between the water molecules.
How does the molecular structure of water molecule affect its polarity?
When the two hydrogen atoms bond with the oxygen, they attach to the top of the molecule rather like Mickey Mouse ears. This molecular structure gives the water molecule polarity, or a lopsided electrical charge that attracts other atoms. The end of the molecule with the two hydrogen atoms is positively charged.
How does the shape of a water molecule contribute to its properties?
Water molecules attract each other due to polarity. Polarity: Although the net charge of a water molecule is zero, water is polar because of its shape. The hydrogen ends of the molecule are positive and the oxygen end is negative. This causes water molecules to attract each other and other polar molecules.
How does the shape of the water molecule affect its polarity?
Polarity of a Water Molecule Water (H2O) is polar because of the bent shape of the molecule. The shape means most of the negative charge from the oxygen on side of the molecule and the positive charge of the hydrogen atoms is on the other side of the molecule. This is an example of polar covalent chemical bonding.
Are larger molecules more polar?
You can be very certain that the larger a molecule is, the more likely it will be somewhat polar, esp. if it contains (so called) hetero atoms.
Why are the bonds in a water molecule polar covalent and how does that affect the interactions between water molecules?
As a result of water's polarity, each water molecule attracts other water molecules because of the opposite charges between them, forming hydrogen bonds. Water also attracts, or is attracted to, other polar molecules and ions, including many biomolecules, such as sugars, nucleic acids, and some amino acids.
How does the polarity of water affect its properties?
Water molecules attract each other due to polarity. Polarity: Although the net charge of a water molecule is zero, water is polar because of its shape. The hydrogen ends of the molecule are positive and the oxygen end is negative. This causes water molecules to attract each other and other polar molecules.

How does the structure of the water molecule shown below enable it to interact with other water molecules?
The structure of water molecule allows it to interact with other molecules. Water's unique emergent properties help make Earth suitable for life. Water is chemically neutral but each end is positive/ negative. Multiple water molecules are attracted to one another– hydrogen bonds.
