When the number of protons and electrons of an atom are unequal the atom?
If an atom has unequal numbers of protons and electrons, it will be charged and is called an ion.
In which way will isotopes of an element always differ?
Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2). Isotopes of a given element contain different numbers of neutrons, therefore, different isotopes have different mass numbers.
Which of the following has negligible mass?
an electron Mass of an electron is very negligible.
What does it mean to say that an atom such as oxygen is highly electronegative?
The fact that oxygen is an atom that is strongly electronegative means that. it more strongly pulls shared electrons toward itself when forming a covalent bond with a less electronegative atom. Ions form when. a very electronegative atom strips a valence electron away from its partner.
What is the relationship between the number of protons and the number of electrons in an atom?
The number of electrons in a neutral atom is equal to the number of protons.
What is it called when there are more protons than electrons?
If it has more protons than electrons,it is a positive ion.
Which describes an atom that has fewer neutrons than protons and more electrons than protons?
An atom that has fewer neutrons than protons and more electrons than protons is a(n) ion.
Do isotopes have different number of protons?
Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons.
Does a proton have negligible mass?
It has a negligible mass and has a charge of –1. Figure 1 Atoms are made up of protons and neutrons located within the nucleus, and electrons surrounding the nucleus. Neutrons, like protons, reside in the nucleus of an atom. They have a mass of 1 and no charge.
Does Gamma Ray have negligible mass?
Gamma rays are energy that has no mass or charge.
What does highly electronegative mean?
Electronegativity refers to the ability of an atom to attract shared electrons in a covalent bond. The higher the value of the electronegativity, the more strongly that element attracts the shared electrons.
What is a result of the unequal electron sharing in a 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.
What is the relationship between the number of protons and the number of electrons in an atom Brainly?
The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.
Why do atoms contain equal numbers of protons and electrons?
When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral.
What happens when there are more proton than electron or more electron than protons in the atom of an element?
Thus, if an atom contains equal numbers of protons and electrons, the atom is described as being electrically neutral. On the other hand, if an atom has an unequal number of protons and electrons, then the atom is electrically charged (and in fact, is then referred to as an ion rather than an atom).
What is the name given to an atom with more or fewer electrons than there are protons?
Definition: An ion is an atom or molecule which has lost or gained one or more electrons, and carries a net electric charge. If the result is an atom with more electrons than protons, the ion is negatively charged. If there are fewer electrons than protons the ion is positively charged.
When the number of electrons is less than the number of proton the charge of the ion is?
When an atom is attracted to another atom because it has an unequal number of electrons and protons, the atom is called an ION. If the atom has more electrons than protons, it is a negative ion, or ANION. If it has more protons than electrons,it is a positive ion.
What will happen when the number of protons is much larger than the number of electrons?
If it has a net charge, (more or less electrons than protons) it is an ion. If it has more electrons than protons it has a net negative charge and is known as an anion. If it has fewer electrons than protons it has a net positive charge and is known as a cation.
What would you call atoms with the same number of protons but different mass?
Two atoms with the same atomic number, but different mass numbers (same number of protons, different number of neutrons), are called isotopes, or isotopic nuclides.
Does isotopes have the same number of protons and electrons?
Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons.
Why number of protons are equal to electrons?
When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral.
How do protons neutrons and electrons differ in terms of their electrical charges and locations within the atom?
Protons have a positive charge. Electrons have a negative charge. The charge on the proton and electron are exactly the same size but opposite. Neutrons have no charge.
What is the difference between beta and gamma rays?
Gamma rays are neutral, while alpha particles have a positive charge and beta particles have a negative charge. Two protons and two neutrons are bound together to form an alpha particle. High-energy electrons are known as beta particles. Gamma rays are photons, which are electromagnetic energy waves.
What is gamma beta and alpha radiation?
Alpha radiation is the name for the emission of an alpha particle in fact an helium nuclei, beta radiation is the emission of electrons or positrons , and gamma radiation is the term used for the emission of energetic photons.
When there is unequal sharing between two atoms of the electrons in a bond which type of bond is it?
polar covalent bond A polar covalent bond is a covalent bond in which the atoms have an unequal attraction for electrons and so the sharing is unequal.
What is Electropositivity and electronegativity?
Electropositive character means the tendency of an atom to lose e− and form a positive ion. Electronegativity of an element is the ability to attract the shared pair of e− in a molecule forwards itself.
What results from unequal sharing of electrons?
Polarity is what results from the unequal sharing of electrons between atoms.
What does unequal sharing of electrons mean?
polar covalent bond This unequal distribution of electrons is known as a polar covalent bond, characterized by a partial positive charge on one atom and a partial negative charge on the other. The atom that attracts the electrons more strongly acquires the partial negative charge and vice versa.
What is the relationship of proton number to the electron number given that the atom is neutral *?
A neutral atom must contain the same number of positive and negative charges, so the number of protons equals the number of electrons. Therefore, the atomic number also indicates the number of electrons in an atom. The total number of protons and neutrons in an atom is called its mass number (A).
Are number of protons and electrons always the same?
Atoms do not always contain the same number of electrons and protons, although this state is common. When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons).
