Which response includes only species that have the electron configuration 1s 2 2s 2 2p 6 3s 2 3p 6 , and no other species?

Cl- K+ Ar and P-3

Explanation:

Hello!

From the electronic configuration we can count 18 electrons.

Na+ has 10 electrons  (11 - 1 = 10)

Cl- has 18 electrons  (17 + 1 = 18)

K+ has 18 electrons  (19 - 1 = 18)

Ar has 18 electrons

Mg+2 has 10 electrons  (12 - 2 = 10)

P-3 has 18 electrons (15 + 3 = 18)

The electrons in the neutral atom are equal to the atomic number.

Negative charges are earned electrons and are added to the atomic number of the element to calculate the total electrons.

The positive charges are assigned electrons and are subtracted from the element's atomic number to calculate the total electrons.

Successes with your homework!

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 .

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
