Prime squares
atomic number (or number of protons)
180 or 288 work If your talking about having 18 factors. Hopefully that's what your talking about.

The atomic number is an identifier for each chemical element.
Itself and any of its factors.
Count the number of protons in its atom.
To identify the valence electrons of an element on the periodic table, look at the group number of the element. The group number indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on.
The upper left number in the symbol of an element on the periodic table represents the atomic number. This number indicates the number of protons found in the nucleus of the atom. Each element has a unique atomic number, which helps to identify and differentiate it from other elements.
The factors of a given number are those numbers which divide into the given number exactly without any remainder. The multiples of a given number are those numbers into which the given number divides exactly with no remainder (that is the given number's times table). example The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 since they all divide into 60 without any remainder The multiples of 60 are: 60, 120, 180, 240, 300, 360, 420, 480, 540, 600, (and so on) since they are all divisible by 60 with no remainder.
The atom's atomic number is equal to the number of protons in its nucleus.For example, an element with 19 protons in its nucleus is Potassium (K), the 19th element on the periodic table.
- Atomic number is equal to the number of protons - Atomic number is equal to the number of electrons (in a neutral atom) - Atomic number is the number of a chemical element in the periodic table of Mendeleev
No, because the number of rows should be a power of 2.
