What are two things added together to get atomic mass?
Number of protons PLUS number of neutrons.
What two things represented in an element's chemical symbol?

Helium with two protons and two neutrons has a atomic number of what?

What is an atomic mass number?
Atomic mass and atomic number are two different things. Atomic mass is the mass of an atom compared to that of hydrogen. The atomic number is the atom's position in the periodic table. It's also the number of protons it has.
How atomic number better than atomic mass?
No two elements may have the same atomic number. But two elements may have same atomic mass. Hence atomic number is better than atomic mass.
What three things are elements on the periodic table usually identified as?
Elements on the periodic table are usually identified by their atomic number, atomic symbol, and atomic weight. The atomic number represents the number of protons in the nucleus, the atomic symbol is a one- or two-letter abbreviation for the element, and the atomic weight represents the average mass of the element's atoms.
What two things can you learn from the atomic number of an element?
From the atomic number of an element, you can learn the number of protons in the nucleus of the atom, which determines the element's identity. The atomic number also reveals the placement of the element on the periodic table based on its number of protons, which impacts its chemical properties.
The atomic number of an atom is determined by the number?
The atomic number is the number of Protons in the nucleus of any particular element. Hydrogen has 1 proton, its atomic number is one; Helium has 2 protons, its atomic number is two; Lithium has 3 protons, its atomic number is three . . . Uranium has Ninety-two protons, its atomic number is 92
How many atomic number are in helium?
The atomic number of the element Helium is two.
What is a sentence with the word atomic number?
"atomic number" is not "the/a" word, it is two words.
