All elements each have an unique atom number (1 to about 104) which equals the number of protons in its nucleus.
The atomic number or the number of electrons is equal to the number of protons.
Mass
The atomic number is the number of protons, and, in a neutral atom, also the number of electrons.
The number of protons is equal to the atomic number of an atom
The number of protons in the nucleus is equal to an elements atomic number, which determines that element's position in the periodic table.
The atomic number or the number of electrons is equal to the number of protons.
You think probable to atomic number, equal to the number of protons in the atomic nucleus.
The number of protons of a chemical element is equal with atomic number.
Mass
The atomic number is equal to the number of protons in the nucleus.
It is equal to the atomic number. Elements are arranged according to atomic number in periodic table
The atomic number is the number of protons, and, in a neutral atom, also the number of electrons.
The elements are arranged according to the atomic number. The number of protons is equal to the atomic number.
This is the periodic table of elements ordered after the atomic number - the atomic number is equal to number of protons in the atomic nucleus. This form of the table is absolutely rational.
Elements are defined by the number of protons they have in their nucleus, known as the atomic number. Each element has a unique atomic number that distinguishes it from other elements on the periodic table.
The number of electrons are equal to the number of protons which is equal to the atomic number. That's if you're trying to find the number of total electrons. If you want to find the number of valence electrons (electrons in the outermost shell) you must look at the group numbers. The group number is equivalent to the number of valence electrons.
The number of protons is equal to the atomic number of an atom
