Why is true about electron dot diagrams
vazorg [7]

Answer: The correct answer is the option: B. An element with eight valence electrons is chemically unstable.

Explanation:

Hello! Let's solve this!

We will analyze each of the options:

A. The group number of the element provides a clue to the number of valence electrons: it is correct, since it provides the number of valence electrons.

B. An element with eight valence electrons is chemically unstable: this is not correct, since elements with eight electrons in the valence shell cannot react because they already have the last complete shell. Therefore, they are chemically stable.

C. The points must be placed one at a time on each side of the chemical symbol: it is correct, because that is the way to make the point diagram.

D. An atom is chemically stable if all the points are paired: this is correct since this verifies that the point diagram has been done well.

We conclude that the correct answer is the option: B. An element with eight valence electrons is chemically unstable.

Hope this helps.....  Stay safe and have a Merry Christmas!!!!!!!!! :D

Describe how nucleic acid basis pair up
castortr0y [4]

The rules of base pairing (or nucleotide pairing) are: A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G)

The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together.
