The atomic number for an element whose mass number is 115, which contains 66 neutrons per atom is: 49

The formula and procedure we will use to solve this problem is:

number of protons = mass number - number of neutrons
atomic number = number of protons

Information about the problem:

mass number = 115
number of neutrons = 66
atomic number =?

Applying the number of protons formula we get:

number of protons = mass number - number of neutrons

number of protons = 115 - 66

number of protons = 49

Applying the atomic number formula we get:

atomic number =number of protons

atomic number = 49

The atom is the smallest part of the composition of matter, it is indivisible and is composed of a nucleus that has protons and neutrons, and around the nucleus there are the electrons.

Explanation:

Aristotle states that an infinite regression in the principle of causality is not possible. If the regression were infinite, then there would never be a first cause (mover), since this would need another mover to start its motion. Therefore, according to Aristotle, there must be an unmoved mover that moves other things, but is not itself moved by any prior action,
