Use the Related Question for how to find the number of protons and electrons in an atom and then add up the number of each atom for each atom in the molecule.
The atomic number of an element is the number of protons in its atoms. In a neutral atom, the number of protons equals the number of electrons.
Find the atomic number. That tells you the number of protons and electrons (in a neutral atom). Then find the atomic weight. The number of protons plus the number of neutrons will equal the atomic weight. So if you know the wt. just subtract the number of protons and you will have the number of neutrons.
In a neutral atom the number of electrons is the same as the atomic number, which is the number of protons in the nucleus.
look at the periodic table and find its atomic number that is the number of protons and electron because their values are the same
The number of protons
The atomic number of the element is the number of protons, therefore there has to be the same amount of electrons to protons.
The number of protons is equal to the number of electrons and the atomic number.
In a neutral atom, the number of electrons is equal to the number of protons of the nucleus.
In a neutral atom, the number of electrons equals the number of protons. The number of protons is the atomic number of the element on the periodic table.
The atomic number of an element is the number of protons in its atoms. In a neutral atom, the number of protons equals the number of electrons.
Kr has the atomic number of 36. It has similar number of electrons and protons.
54 protons, an average of 77 neutrons, and 54 electrons.
valence electrons is the same as the number as the last digit in the group :)
By the addition of the number of protons and the number of electrons
Find the atomic number. That tells you the number of protons and electrons (in a neutral atom). Then find the atomic weight. The number of protons plus the number of neutrons will equal the atomic weight. So if you know the wt. just subtract the number of protons and you will have the number of neutrons.
101 electrons...to find the number of electrons in an element, you need to know the number of protons. There are the same amount of protons as electrons. The number of protons is the same number as the atomic number. Mendelevium has 101 as its atomic number therefore 101 protons and therefore 101 electrons.
in an atom of neutral charge, the number of electrons will be the same as the number of protons, or the atomic number.
