When is an atom most stable?
Answer When the outermost shell(valence shell) is filled the atom is to be most stable. First Shell: holds up to 2 electrons Second Shell: holds up to 8 electrons Third Shell: holds up to 18 electrons Fourth Shell: holds up to 32 electrons
What role do valence electrons play in formation of bonds?
Valence electrons are electrons on the outermost "level". And depending on its electron configuration, it plays a role in which if the atom requires to gain or lose electrons in order to become "stable", it can accept or give electrons to another atom in a chemical reaction.
What is a atom with its outermost shell completely filled in likely to do?
They are most likely to lose or gain atoms. For example if u have two atoms with uneven electrons then one of the two will take the other one's to balance each other out.
Why do atoms tend to bond to other atoms?
When two atoms need to gain same amount of electrons, they tend to share. That is when bonds are formed. Ex. One atom of oxygen needs two electrons to attain its octet. Another atom of oxygen will also need two electrons. Since both the atoms need electrons they begin to share their electron in the outermost shell. They form double bond since they need two electrons.
How man electrons would you need to fill the outermost ring of hydrogen?
1: The outermost ring of hydrogen is the s-level, which can contain only two electrons, and a hydrogen atom itself already has one of these electrons.
How many electrons does neutral selenium atom need to fill outermost shell?
Selenium needs two more electrons.

A helium he atom has 2 electrons that are both in the outermost energy level how many more electrons does the atom need to fill its outermost energy level?
It is the most stable element in the universe and does not need anymore electrons. Its outermost energy level is full.
What atom has single electrons in its outermost shell?
Well, all the halogens have 7 valence electrons, the ones in the outermost shell, so elements like fluorine, iodine, and chlorine all need 1 electron to fulfill their octet and become stable.

How many electrons does carbon need to have the outermost energy shell filled?
Carbon needs to have 8 electron in its outermost shell to have it completely filled, 4 more valence electrons than it has in the neutral for of carbon.
What does atoms have to do to fill the outermost energy level?
they need to either gain or lose electrons to create an octet. It depends on the atom. an octet is when an atom has a full outermost energy level
How many electrons does an atom need in its outer shell to be stable?
5
Does an atom need 8 electrons in its outer shell to be stable?
YES!
