Question

In an electron dot diagram, the symbol for an element is used to represent

Answer 1

A the nucleus bruh it can't be anything else

Answer 2

Answer : The correct option is, (A) the nucleus.

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 electron dot symbol.

In an electron dot diagram, the symbol for an element is used to represent the nucleus.

For example :

As we know that arsenic has '5' valence electrons. So, the symbol (As) is used to represent the nucleus and valance electrons around the is represented by the 'dot'.

The Lewis-dot structure of As (arsenic) is shown below.
