Which number determines the chemical properties of an element?
number of protons The chemical properties of an element are determined by the number of electrons in its atom, which in turn is determined by the number of protons.
Which electron determine the chemical property of an element?
Valence electrons Valence electrons determine the chemical properties of an element, or how the valence electrons of one element are shared or traded with valence electrons of other elements to create new molecules.
What determines properties of elements?
Chemical properties of each element are determined by the element's electron configuration, and particularly by the number of electrons present in its outermost shell.
What determines the chemical bonding properties of an atom?
The number of electrons in each element's electron shells, particularly the outermost valence shell, is the primary factor determining its chemical bonding behavior.
What determines an element’s chemical properties quizlet?
The chemical properties of an element, are determined by the number of protons in the nucleus. This number of protons is called the atomic number. The mass of the atom, its atomic mass, depends upon the sum of the number of protons and the number of neutrons present in the nucleus.
How does the number of electrons affect the chemical properties of the atom?
The properties of an atom relate directly to the number of electrons in various orbitals. Valence electrons, the electrons in the outermost or valence shell, are important as they provide insight into an element's chemical properties and are the ones gained, lost, or shared during a chemical reaction.
Do electrons determine chemical properties?
Electrons located in the outermost shell of the electron cloud are called “valence electrons” and have the highest energy. Valence electrons determine the chemical properties of an element.
What determines the chemical behavior of an element?
The chemical behavior of atoms is determined by the number and the configuration of the electrons in the atom. Why should one bother to discuss the nucleus? The number of protons in the nucleus determines the number of electrons in the atom.
What does the number of electrons determine?
The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms.
Which number determines the chemical properties of an element quizlet?
The chemical properties of an element, are determined by the number of protons in the nucleus. This number of protons is called the atomic number. The mass of the atom, its atomic mass, depends upon the sum of the number of protons and the number of neutrons present in the nucleus.
What does the chemical properties of an element depend on?
the chemical properties of an element depend very heavily on the number of electrons the atoms of this element have in their outermost energy level.
What determines the chemical properties of an element quizlet?
The chemical properties of an element, are determined by the number of protons in the nucleus. This number of protons is called the atomic number. The mass of the atom, its atomic mass, depends upon the sum of the number of protons and the number of neutrons present in the nucleus.
What does the chemical property of an atom depend on?
The chemical properties of an atom depend upon the atomic number. From the atomic number, we can get valence electrons that determines the chemical properties of it.
Do electrons determine the element?
An element and its location in the periodic table is determined according to the number of protons in the nucleus. The electrons influence the atom's electric charge.
How do you determine the number of electron shells?

Which property determines the chemical reactivity of an element?
The number of electrons in the outermost shell of an atom determines its reactivity.
Is the number of protons in the nucleus of an atom which determines the chemical properties?
The number of protons in the nucleus of an atom is its atomic number (Z). This is the defining trait of an element: Its value determines the identity of the atom. For example, any atom that contains six protons is the element carbon and has the atomic number 6, regardless of how many neutrons or electrons it may have.
What does the electron shell do?
Electrons in outer shells have higher average energy and travel farther from the nucleus than those in inner shells. This makes them more important in determining how the atom reacts chemically and behaves as a conductor, because the pull of the atom's nucleus upon them is weaker and more easily broken.
What determines an atom’s chemical behavior?
The chemical behavior of atoms is determined by the number and the configuration of the electrons in the atom. Why should one bother to discuss the nucleus? The number of protons in the nucleus determines the number of electrons in the atom. Most atoms in the world around us are electrically neutral.
What does number of electrons determine?
The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms.
What is outermost shell in chemistry?
This outermost shell is known as the valence shell, and the electrons found in it are called valence electrons. In general, atoms are most stable, least reactive, when their outermost electron shell is full.
How many electrons are in outer shell?
The outermost shell in an atom cannot have more than eight electrons even if it has a capacity to take up more electrons. This is also called the octet rule. Protons and neutrons have nearly same mass(one unit).
What does the number of electrons in the outermost shell of an element indicate?
The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms. This outermost shell is known as the valence shell, and the electrons found in it are called valence electrons.
What determines the chemical properties of an atom quizlet?
The chemical properties of an element, are determined by the number of protons in the nucleus. This number of protons is called the atomic number. The mass of the atom, its atomic mass, depends upon the sum of the number of protons and the number of neutrons present in the nucleus.
What is outer shell in chemistry?
This outermost shell is known as the valence shell, and the electrons found in it are called valence electrons. In general, atoms are most stable, least reactive, when their outermost electron shell is full.
Why are the outermost electrons important?
Valence electrons are the outermost electrons of an atom. These electrons are important as they govern that atom's electronegativity, electron affinity, and ionization energy, which leads to things such as covalent and ionic bonds.
What do electrons determine?
The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms.
Why do electrons determine the chemical behavior of an atom?
The electrons in the energy levels with the highest number are, on average, the farthest from the nucleus. Because differences in electrons located in the outermost level distinguish an atom from its nearest noble gas, these are the electrons responsible for the atom's chemical behavior.
What is electron shells in chemistry?
An electron shell is the outside part of an atom around the atomic nucleus. It is a group of atomic orbitals with the same value of the principal quantum number n.
Why do atoms want full outer shells?
Atoms want a full outer shell because it completes all the gaps in the outside. With no gaps, other electrons don't want to fit into those spaces. For example, a noble gas like Neon has a full outer shell. It doesn't react with other chemicals because the electrons from other chemicals can't fall in anywhere.
