The table compares some characteristics of two atoms.
Charged Particles
Atom Number of Neutrons Mass Number
Х
10
19
Y
8
16
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 poin
O Atom X and Atom Y are isotopes.
Atom X and Atom Y are in the same family.
Atom X is in a row below Atom y on the periodic table.
O
Atom X is in a column to the right of Atom y on the periodic table.

Answer 1

Atom X is in a row below Atom Y on the periodic table.

Step-by-step explanation:

We know that mass increases as the atomic number increases, and depends primarily on the number of protons and neutrons in the atoms. So mass should increase across periodic table rows from left to right and down periodic table columns. The most accurate answer would be "Atom X is a row below Atom Y on the periodic table," since it's atomic mass (the mass of Atom X) is higher than that of Atom Y's, thus making it lower on the periodic table.

Also I got it right on the test lol. Hope this helps (;
