What can we calculate in an atom?

Atoms are beautifully arranged on the periodic table: with our atom calculator, we will peek into them, learning how to find the atomic number, calculate the number of protons, neutrons, and electrons, and how to calculate the mass of an atom.

How do you find the atomic mass of an atom?

The chemical element of an atom is determined by the number of protons, also known as the ‘atomic number (Z)’ of the nucleus. The element oxygen has an atomic number Z=8, while carbon has Z=6. The ‘atomic mass’ of the nucleus is given by A=Z+N, where N is the number of neutrons in the nucleus.

How do you find the number of atoms in a formula?

REMEMBER: Subscripts represent the number of atoms of an element. When there is no subscript written, it is understood that the element has only one atom in the formula. To solve, multiply 3 to 6 then, copy the base and the exponent. Cancel the same units in the equation. Another example, how many moles are present in 2 x 10 24 molecules of water?
