Answer:
B) protons
Explanation:
The total number of protons in an atom represents the atomic number of that element. An element is generally expressed as
Where,
A is the element
N is the Mass number i.e., the number of neutrons and protons in an atom.
Z is the atomic number.
The elements are arranged according to their atomic number in the modern periodic table.

Answer:
The magnitude of the force will decrease
Explanation:
The gravitational force is one of the four fundamental forces of nature. It is an attractive force exerted between every object having mass.
Its magnitude is given by the equation:
where
G is the gravitational constant
m1 is the mass of the first object
m2 is the mass of the second object
r is the separation between the objects
As we see from the equation, the magnitude of the gravitational force is inversely proportional to the square of the distance between the objects:
Therefore, this means that as the distance between two bodies increases, the gravitational force will decrease.
