Molecules that form when electrons are shared unequally between atoms are called?
Valence electrons
How many electrons are in a completed valence shell of most second period atoms when they combine with other atoms to become molecules- 2 or 4 or 6 or 8?
The first two elements in the 2nd period are metals, and form ionic compounds rather than molecules. Boron, carbon, nitrogen, oxygen, and fluorine share electrons, forming covalent bonds with other nonmetals so that they will each have a full valence shell with eight electrons. The noble gas neon already has eight valence electrons and is generally nonreactive.
What chemical do valence electrons make when sharing?
Molecules or covalent compounds are formed by the sharing of valence electrons.
What determines chemical bonding in an element?
Atoms hold their electrons in valence shells, but each shell only holds so many electrons. If an atom's outer valence shell is full, it's inert (does not form bonds). If it's outer shell isn't full, then it will form bonds.
Atoms tend to combine with each other in a way that each atom will have eight?
Electron Shells no it needs 8 valence electrons Wrong. In order for a atom to combine it must need 8 element molecules.
What is shared when elements combine to form compounds?
Electrons are shared when elements combine to form molecules.

What happens to the number of valence electrons when atoms combine to form a compound?
They Share Electrons
Which electrons are shared in molecules?
In metallic bonding, the valence electrons freely 'jump' from atom to atom, forming kind of an electron sea.
What determines chemical bonding in an element?
Atoms hold their electrons in valence shells, but each shell only holds so many electrons. If an atom's outer valence shell is full, it's inert (does not form bonds). If it's outer shell isn't full, then it will form bonds.
How many valence electrons can combine with other elements?
all the electrons that are available in outermost shell
Atoms tend to combine with each other in a way that each atom will have eight?
Electron Shells no it needs 8 valence electrons Wrong. In order for a atom to combine it must need 8 element molecules.
What is the term use for a completed outer shell of 8 electrons?
The most common term for a completed outer shell of electrons is that is or has "full" valence electrons.
Which electrons can form diatomic molecules joined by a single covalent bond?
The valence electrons
How many total valence electrons does NaCl have?
The NCl3 molecule, like most other stable molecules, exist because they share electrons in such a way as to close out the valence shell. Therefore, although one usually doesn't say so in regards to molecules, NCl3 has 8 valence electrons.
