Which of the following accurately describes properties of valence?
a. the smaller the number of electrons an atom has to borrow or to lend, the greater the activity of the atom.
b. metals tend to have a negative valence and tend to be electron borrowers.
c. the greater the number of electrons an atom has to borrow or to lend, the greater the activity of the atom.
d. nonmetallic elements tend to have a positive valence and tend to be electron borrowers.

Option (A) is the correct answer.

Explanation:

Valence electrons are defined as the electrons present in the outermost shell of an atom.

Smaller is need for valence electrons to be borrowed or to lend more is the reactivity of an atom.

For example, atomic number of fluorine is 9 and its electronic distribution is 2, 7.

So, it just needs one more electron in order to gain stability. Therefore, it will be highly reactive in nature.

Thus, we can conclude that the smaller the number of electrons an atom has to borrow or to lend, the greater the activity of the atom, accurately describes properties of valence.

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
