Which describes a step in the process of forming an ionic bond?

a.) a metal atom loses electrons and becomes a positive ion.

b.) a metal atom gains electrons and becomes a negative ion.

c.) a nonmetal atom loses electrons and becomes a negative ion.

d.) a nonmetal atom gains electrons and becomes a positive ion.

Option (A) is the correct answer.

Explanation:

A bond formed by donating electrons from one atom to another then the bond formed is known as ionic bond.

For example, sodium has one extra electron as its electronic configuration os 2, 8, 1 and chlorine has shortage of one electrons as chlorine's electronic configuration is 2, 8, 7.

So, sodium will donate one electron to chlorine atom and sodium itself will become positively charged ions. Therefore, it will result in the formation of NaCl by forming an ionic bond.

Thus, we can conclude that a metal atom loses electrons and becomes a positive ion describes a step in the process of forming an ionic bond.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
