Question

an element E combines with oxygen to form an oxide E2O which is a good conductor of electricity give the following information how many electrons will be present in the valence shell of the element E write the formula of the compound formed when the element combines with chlorine​

Answer 1

Answer:

Element E is Sodium (Na) on combining with oxygen it forms NA2O.

As atomic number of sodium is 11

So its electronic configuration is 2,8,1

Electrons present in its valence shell is 1.

When it combines with chlorine it forms sodium chloride (common salt)

2Na + Cl2 ----------- 2NaCl
