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.

c- cold periods in earth's history during which glaciers covered much of the surface.

explanation:

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
