Which p-block element has 4 valence electron and is in the third period?
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.
Which of the representative elements in period 4 has 3 valence electrons?
The representative element in period 4 with 3 valence electrons is phosphorus.
How does the number of valence electrons for element change across a period?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
What element is found on period 4 and has 7 valence electrons?
Only nitrogen (but in the period 2) has 7 electrons in the neutral atom.
How can you predict and element's group and period?
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
What is the representative element in period 4 with six valence electrons?
Sulfur (S) is the representative element in period 4 with six valence electrons.

What is in period 3 and has 5 valence electrons?
Phosphorus (P) is in period 3 of the periodic table and has 5 valence electrons.
What is the element in period 3 with 6 valence electrons?
Selenium. As you go across the groups, not counting the transition metals, a valence electron is added.
Which period 5 element has 5 valence electrons?
Antimony (Sb, # 51) has 5 valence electrons (and so do all the other elements in that group.)
Which element in period 5 has 2 valence electrons?
silver :)
What is the same for every element in the same period?
The number of electrons in its valence shell
What is the number of valence electrons (number in the outer most energy level)?
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
