Metals, particularly alkali and alkaline earth metals, will always lose valence electrons to become ions. For example, sodium (Na) and calcium (Ca) readily lose their outermost electrons to achieve a stable electron configuration, forming positive ions (cations) in the process. This tendency is driven by their desire to reach a full outer electron shell, similar to that of noble gases.

What are the electrons in the outmost shell of an atom called?
the electrons in the outermost shell of an atom are considered to be the valence electrons.
The outermost electrons in an atom are called?

How does a atom become stable?
When the atom has 8 valence electrons.

How many valence electrons does a nitrogen atom have then a carbon atom?

How many valence electrons are in an atom of magnesuim?
There are 2 valence electrons in an atom of magnesium. There are 5 valence electrons that are in an atom of phosphorus. There are 4 valence electrons that are in a silicon atom.
Which electrons are the valence electrons of an atom?
The electrons farthest away from the nucleus are the valence electrons of an atom.
If an atom has four valence electrons is it an anion?
No, having four valence electrons does not determine whether an atom is an anion. An anion is formed when an atom gains electrons to have a negative charge. If the atom with four valence electrons gains four more electrons, it would become an anion.
