Which of these elements will successfully create a 1:1 bond with Carbon (C) Carbon (C)
Silicon (Si)
Beryllium (Be)
Oxygen (0)

Option B, Silicon

Explanation:

The valency of Carbon is 4 as it has four electrons in its outermost shell

The valency of Si is also four hence C

Hence Silicon can form 1:1 bond with the carbon

Valency of Beryllium is 2, hence it can not form 1:1 bond with carbon. Similarly the valency of oxygen and carbon are way different to form 1:1 bond

hence, only option B is correct

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.

so what is the problem with your lab report and whats the subject of the lab report? i will you
