The partial electron configuration of an atom with 11 electrons is shown. 1s22s22p6x which of the following does x represent?

Atomic number of an atom is equal to number of electrons or protons present in system. In present case, the atomic number is 11. It implies there are 11 electrons associated with the system.

Further, electronic configuration represents distribution of electrons in atoms. Thus in present case electronic configuration of atom is  1s2 2s2 2p6 3s1.

C) X represents 3s1

Explanation:

I took the test and that was the right answer.

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.

hope this .

he would use the colour black
