How many atoms of each element are in the following? a. ch4 b. mg3(po4)2

a). 5 atoms

b). 13 atoms

Explanation:

Atoms: It is the smallest unit of the element.

Atomicity : Total number of atoms present in the molecule. For e.g each molecule of [tex]N_{2}[/tex] gas contain 2 atoms of nitrogen.

[tex]CH_{4}[/tex] = 1 atom of C + 4 atoms of H

                                 = 5 atoms

[tex]Mg_{3}(PO_{4})_{2}[/tex]

= 3 atoms of Mg + (1 atom of P + 4 atoms of O )[tex]\times2[/tex]

= 3 +5 [tex]\times 2[/tex]

= 3 + 10

= 13 atoms

yes they ca   is ur ansswerrr

b is the correct answer

mark me brainliest and hope this
