Y 7 13
Use the table to determine the number of protons for each atom. Then, choose the statement below that is true about the two atoms. (5 points)

a
Atom X and Atom Y are in the same row, but not the same family, on the periodic table.

b
Atoms X and Atom Y are in the same family, but not the same row, in the periodic table.

c
Atom X is in a column to the right of Atom Y in the periodic table.

d
Atom X and Atom Y occupy the same position in the periodic table because they are isotopes.

d . Atom X and Atom Y occupy the same position in the periodic table because they are isotopes.

Explanation:

Atomic number is equal to the number of protons.

Mass number is the sum of number of neutrons and number of protons.

Given : For Atom X :

Number of neutrons= 6

mass number of X = 12

Mass number =  number of neutrons + number of protons

Number of protons of X = Mass number - number of neutrons = 12- 6= 6

For Atom Y :

Number of neutrons= 7

mass number of X = 13

Mass number =  number of neutrons + number of protons

Number of protons of Y = Mass number - number of neutrons = 13 - 7 = 6

The atomic number is specific to an element, and the element with atomic number 6 is carbon . Thus atoms X and Y are isotopes which have same atomic number but different mass number.
