Which element has the greatest number of valence electrons available for bonding? selenium boron calcium chlorine

Answer : The correct option is, Chlorine

Explanation :

The given elements are, Se, B, Ca, Cl

Atomic number = 34

Group number = 16

General Electronic configuration of the group number 16 elements is, .

The general configuration shows the number of valence electrons are present in the element.

The number of valence electrons present = 2 + 4 = 6

Atomic number = 5

Group number = 13

General Electronic configuration of the group number 13 elements is, .

The number of valence electrons present = 2 + 1 = 3

Atomic number = 20

Group number = 2

General Electronic configuration of the group number 2 elements is, .

The number of valence electrons present = 2

Atomic number = 17

Group number = 17

General Electronic configuration of the group number 17 elements is, .

The number of valence electrons present = 2 + 5 = 7

From this we conclude that the chlorine is the element which has the greatest number of valence electrons available for bonding.

Hence, the correct option is, Chlorine.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
