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 atomic number is equal to the number of electrons(-) and protons(+): that is why elements have no charge, as a neutron is neural
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.
The mass number of an isotope of an element is equal to its atomic mass number. However, the atomic weight of an element is a weighted average of the isotopes that occur in the element in nature. Because almost all elements have more than one naturally occurring isotope (if they have any), the atomic weights of most elements are not integers, as mass numbers always are.
the atomic number is equal to the number of electrons(-) and protons(+): that is why elements have no charge, as a neutron is neural
1. The molecular mass of a compound is the sum oh the atomic weights of the elements contained in the molecule of this compound. 2. The atomic number of an element is the number of this element in the Periodic Table of Mendeleev; the atomic number is equal to number of protons and electrons.
