It is the number of protons in the nucleus of the atom and it determinnes many properties of the atom. The atomic number is also the number of electrons and is a constant for every element
Atomic numbers represent the number of protons in an atom's nucleus. It also defines the element, as each element has a unique atomic number.
Scientists use the symbol "u" to represent atomic mass unit.
The atomic number is the number of protons found in the nucleus of an atom.Also, if in it's pure elemental form, the number of electrons.
it represents where the atoms, protons, Atomic Mass, atomic number, and electrons where they are located on the nucleus.
The number of protons and electrons of the atom in a neutral state.
Atomic numbers represent the number of protons in an atom's nucleus. It also defines the element, as each element has a unique atomic number.
It represents the atomic number and atomic mass. Mass number is the superscript Atomic number is the subscript
atomic number
Its atomic number - how many protons it has.
Atomic number= number of protons. Hydrogen atomic number=1
Scientists use the symbol "u" to represent atomic mass unit.
No element has this atomic number. All atomic numbers are whole numbers.
either mass or protons the top is the atomic number it shows how many protons the bottom number is the atomic mass also the weight
The atomic number is the number of protons in nuclei of the atoms of a given element.
atomic mass
The atomic mass number must be higher as that represent the number of protons and neutrons in an element. Whereas only the number of protons are represented in the Atomic Number.
The numbers on Mendeleev's periodic table represent the atomic number of each element, which is the number of protons in the nucleus of an atom. This number determines the element's identity and its placement in the periodic table.
