Question

Which of the following is the correct Lewis structure diagram for Neon? The letters Ne with eight dots The letters Ne with seven dots The letters Ne with six dots The letters Ne with five dots

Answer 1

Answer:

Ne with eight dots

Explanation:

On the periodic table, Neon is in group 8A. The group can be used to determine the number of valence electrons.

The dots in the Lewis structure diagram represent the number of valence electrons.

Answer 2

Answer : The correct option is, The letters Ne with eight dots.

Explanation :

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

The representation of valence electrons of an atom by dots around the symbol of an element is said to be the Lewis-dot symbol.

In the representation of Lewis-symbol, one electron dot must put on each side of the element symbol then paired the electrons.

The given atom is, neon (Ne)

The electronic configuration of neon atom is,

$1s^22s^22p^6$

As we know that neon has '8' valence electrons.

The Lewis-dot structure of neon atom is shown below.
