If an element has three isotopes with known natural abundance percentages, what other information is needed to find the average atomic mass of the
element?
A. The average mass of the isotopes
B. The atomic number of each isotope
C. The mass of each isotope
D. The sum of the masses of the isotopes

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

hope it

and ur welcm

: )

h let me think

answer; /// i do believe that the correct answer is (c)nuclear bond
