How many neutrons would a element that has a atomic number of 22 and a atomic mass of 40 have? (this is not based on a element found in the periodic table)

18

40

22

20

18

Explanation:

The mass is equal to the total number of prtons and neutrons

G is called the constant of gravitation and is equal to 6.67 × 10−11 newton-metre2-kilogram−2.

Explanation:

In SI units, G has the value 6.67 × 10-11 Newtons kg-2 m2. The direction of the force is in a straight line between the two bodies and is attractive. Thus, an apple falls from a tree because it feels the gravitational force of the Earth and is therefore subject to “gravity”.
