According the lewis dot structure shown here, how many valence electrons does chlorine have?

Answer : The number of valence electrons present in chlorine is, 7

Explanation :

Lewis-dot structure : It is also known as electron-dot structure. Lewis-dot structure shows the bonding between the atoms of a molecule and it also shows the number of unpaired electrons present in the molecule.  The number of valence electrons are shown by 'dot' in the structure.

The given molecule is, chlorine

As we know that the chlorine belongs to group 17 that means it has 17 electrons.

The electronic configuration of chlorine is,

From this we conclude that the number of valence electrons present in chlorine is, 7

The Lewis-dot structure of chlorine is shown below.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
