Zinc is [Ar] 3d104s2 so there are 2 valence electrons.
it has 2 valence electron in its outer shell
Zinc donates its two valence electrons (in the 4s sub-shell) to form its stable ions. However, in rare occasions, such as in diethylzinc, it shares those two electrons with other atoms.
It loses 2 valance electrons.
2 valence electrons.

Antimony has 5 valence electrons.
Two electrons will fill a hydrogen's outer, or valence, shell.
Helium (He) has 2 electrons in its outer shell. Calcium (Ca) has 2 electrons in its inner shell and 8 electrons in its outer shell.

In the first shell there are two electrons and in the second shell there are six electrons, but only the electrons in the second (outer) shell are valence electrons.
4V V-Valence Electrons Valence Electrons-Last electron (which is on the outer shell)
There are 2 electrons in valence shell of calcium. :-)
2 valence electrons
it needs six more electrons to have a full outer valence shell.
Argon has 8 valence electrons (electrons in the outer shell)
Argon has eight valence (outer) shell electrons. It is a Noble Gas so its valence shell is full (Octet Rule).
6 valence electrons.
Antimony has 5 valence electrons.
The outer valence shell of a sulfur atom contains a total of 6 electrons: two 3s electrons and four 3p electrons.
It depends what number the shell is, valence just means 'outer'
Sulphur has 16 electrons. Correction: there is 16 in total, but 6 in the outer (valence) shell.
Here are seven valence electrons.
