B.the element has 4 valence electrons
C. The element has 4 electrons
D. The element has 14 protons

Sagot :

For a particular element if only the group number of 14 is known then the element has 4 valence electrons.

What is valence electron?

Valence electron is defined as the number of electrons which an atom must lose or gain to attain the nearest noble gas or stable electronic configuration. “Electrons in the outermost shells that are not filled are called valence electrons”.

The valence electrons are termed as the part of the chemical reactions as they contain more energy as compared to the electrons present in inner orbits. Meanwhile, the number of valence electrons which present also helps us to determine a specific element’s chemical properties, such as its valence or valency, the formation of bonds with other elements.

Determination of valence electron

One of the most simple way to find valence electrons is

valance electron = group number (13-17) -10

For group number 14

valence electron = 14-10

= 4

Thus we find that the number of valance electron is 4.
