The number of protons (or electrons) an atom has. To find out how many neutrons there are take the atomic number and subtract it from the Atomic Mass...
(Atomic Mass)-(atomic number)= neutrons
atomic number= #of protons (or #of electrons)

Maxinedepends on the atom... Ordinary matter is made up of protons, neutrons, and electrons and is composed of atoms. An atom consists of a tiny nucleus made up of protons and neutrons, on the order of 20,000 times smaller than the size of the atom. The outer part of the atom consists of a number of electrons equal to the number of protons, making the normal atom electrically neutral.
A chemical element consists of those atoms with a specific number of protons in the nucleus; this number is called the atomic number. The atoms of an element may differ in the number of neutrons; atoms with different neutron numbers are said to be different isotopes of the element.
Elements are represented by a chemical symbol, with the atomic number and mass number sometimes affixed as indicated below. The mass number is the sum of the numbers of neutrons and protons in the nucleus.Oxygen, hydrogen, nitrogen are all elements.
An element's atomic number represents the number of protons in the nucleus of an atom of that element. It also determines the element's position on the Periodic Table.

What do the numbers on the elements mean?
The numbers on the elements represent their atomic number, which indicates the number of protons in the nucleus of an atom. This number is unique to each element and determines the element's identity. Additionally, the atomic number can help determine the element's position on the periodic table and its chemical properties.
How do scientists represent the elements?
Scientists represent elements using the periodic table, which organizes elements based on their atomic number, electron configuration, and chemical properties. Each element is represented by a unique symbol typically derived from its name in Latin or another language.
Are elements in a period arranged alphabetically?
NO!!! Elements in a Period are arranged by Atomic No. / Proton No. If we take PERIOD 1. . the two elements are Hydrogen and Helium, in that order. H**ydrogen , Hel**ium are NOT in alphabetical order.
What are the big numbers called on the periodic table?
The big numbers on the periodic table are called atomic numbers. They represent the number of protons in the nucleus of an atom, which determines the element's identity.
The periodic law states that the properties of elements will repeat when the elements are arranged by _______.?
If the elements are arranged in the order of their increasing atomic numbers, there properties are repeated in a periodic manner.
