So, all you have to look at is at the atomic number of the elements on the periodic table, which it is at the top of the symbol on the P.T, and that is the number of protons and electrons! Now, to find the number of neutrons, you have to find the number at the bottom of the element symbol called the atomic mass no. and you take away that by the top number.
350 is an abundant number.

A perfect number is one with factors (apart from itself) that sum to give the original number. An abundant number is one where this sum is greater than the original number. A deficient number is one where the sum is less than the original number. The factors of 75 are 1, 3, 5, 15 and 25. The sum of these numbers is 49. Thus 75 is a deficient number.
