Name an element which has a total of three shells and there are four electrons in its valence shell.
Name an element which has a total of three shells and there are four electrons in its valence shell.
The elements in periodic table are placed in periods and groups. Periods are horizontal rows that has increasing atomic numbers. Groups are vertical columns. The groups have similar chemical properties. There are 7 periods and 18 groups in periodic table.
The outermost shell is the valence shell of the element. The elements in groups have similar electronic configuration of the valence shell.
Step-1:
Number of valence electrons in the valence shell = 4
Number of valence electrons + 10= Number of group
So, the element belong to group 14.
Step-2:
Number of valence shell = 3
Number of valence shell = Number of period
So, the element belong to period 3.
Final answer:
Therefore, the element that has total of three shells and four electrons in valence shell is Silicon (Si).
Silicon belongs to period 3 and group 14.
