Silicon is p-block element. It has 4 valence electrons. It is present in group-14.Titanium has 4 valence electrons. It is in the third period. Titanium is a metal element.
The representative element in period 4 with 3 valence electrons is phosphorus.
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
Only nitrogen (but in the period 2) has 7 electrons in the neutral atom.
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
Sulfur (S) is the representative element in period 4 with six valence electrons.

The element in period 3 with 6 valence electrons is sulfur (S). Sulfur is in group 16, so it has 6 valence electrons in its outer shell.
Phosphorus (P) is in period 3 of the periodic table and has 5 valence electrons.
The representative element in period 4 with 3 valence electrons is phosphorus.
The element from period 5 with 5 valence electrons is nitrogen (N).
silver :)
Two electrons imply that the element is in the second period. The 4 valence electrons says that it is located in group 4A (or group 14 in modern notation). Hence, this element is carbon.The element has 2 electron shells means the element is in the 2nd group. This element is carbon. It has 4 valence electrons.
The valence electrons are the outer most electrons and the principal energy level in which they belong will vary for element to element and generally corresponds to the period number in which the element is present
