What is the ground state electron configuration for sodium (Na)?

Na has a ground-state electronic configuration of 1s2 2s2 2p6 3s1. Removing the 3s electron leaves us with the noble gas configuration 1s2  so a sodium ion is Na+.

Explanation: I HOPE THAT HELPED!

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
