The chemical properties of an atom depend on the number of what?

The chemical properties of an atom depend on the number of electrons in its outermost shell, known as the valence electrons. These electrons determine how atoms interact with other atoms to form chemical bonds.


What are the electrons in the outermost electron shell or orbital called?

The electrons in the outermost shell or orbital are called valence electrons. These electrons are involved in forming chemical bonds with other atoms.


Why it is said that outermost shell should contain 8 electrons?

According to the Octect Rule, an atom is most stable when its outermost shell has 8 electrons. So atoms try to attain 8 electrons in their outer shell.


Which electrons are use to form bonds?

Valence electrons are the electrons that are used to form bonds between atoms. These are the electrons in the outermost shell of an atom.


How many electrons does a sulfur have in its outermost shell?

Sulphur has 6 electrons in its outermost shell.


What are electrons in the outermost energy shell of an atom called?

Electrons in the outermost energy shell of an atom are called valence electrons. These electrons determine the chemical properties of the atom and are involved in forming chemical bonds with other atoms.


What are the electrons the outermost shell of an electron called?

Valence electrons are the electrons in the outermost shell of an atom. The ones in the inner shell are known as core electrons.

How many electrons will thallium has in its outermost shell?

thallium has 3 electrons in outermost shell.


What determines whether or not an atom reacts with other atoms is it the electrons on the first shell or the second?

It is predominantly the electrons on the outermost shell (valence electrons) of an atom that determine its reactivity with other atoms. These valence electrons are involved in forming chemical bonds with other atoms.


Where would you find valence electrons?

They are the electrons in the outermost shell, and are the ones involved in most chemical reactions.
