The number of valence electrons increases with increase in atomic number from the beginning to the end of period 2. The maximum number of valence electrons possible in any outermost shell is 8.
Only nitrogen (but in the period 2) has 7 electrons in the neutral atom.
Helium has 2 electrons (total of 2 electrons and 2 valence electrons)
Group No = No.of valence electrons in the outer configuration period No = principle quantum No.(n)of the last shell of outer configuration Eg:carbon EC=1s2 2s2 2p2 No.of valence electrons=4, indicates G.No.is IV n=2, indicates period No. is 2 chlorine EC=3s2 3p5 valence electrons=7,so G.No. is VII n=3,so period No is 3
The element with 2 valence electrons and 4 protons is beryllium. Beryllium has an atomic number of 4, indicating it has 4 protons in its nucleus. The valence electrons are the outermost electrons in an atom, and beryllium has 2 valence electrons in its outer energy level.
To determine the number of valence electrons for an element on the periodic table, you look at the group number of the element. The group number tells you how many valence electrons the element has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.

There are 2 valence electrons in cobalt.

Calcium is a non metal element. There are 20 electrons in a single atom.
All alkali earth metals have 2 valence electrons.
To identify the valence electrons of an element on the periodic table, look at the group number of the element. The group number indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on.
