The atomic number is the number of protons in the nucleus of any atom of any element. Because all atoms are neutral, the number of protons = number of electons. So the atomic number is the number of electrons. You may be confusing an atom with an ion. Atoms of elements on the right side of the Periodic Table have a stronger attraction for electrons than atoms of elements on the left side, For example, when a chloride atom get close enough to an atom of Sodium, the electron in the outer shell of the Na atom will move to the outer shell of the Cl atom. Now the Cl atom has 17 protons and 18 electrtons making a -1 charged ion. The Na atom now has 11 protons and 10 electrons making a +1 charged ion.
Elements in column 1 of the periodic table form +1 ions.
Elements in column 2 of the periodic table form +2 ions.
Elements in column 7 of the periodic table form -1 ions.
Elements in column 6 of the periodic table form -2 ions.

How would you find valence electrons in a periodic table?
the group number of the periodic table shows the valence electron. such as :- sodium is placed in group 1 and have valence electron.
Which way does electron shells increase on the periodic table?
The number of shells in periodic table increase down the group, i.e., vertically.
Why is hydrogen the first element?
As the periodic table is arranged in order of increasing atomic number hydrogen is the first element in the periodic table as it has only one electron.
How does the bohnr model of the atom relate to the periodic table?
The quantum number of the highest occupied electron orbital in a Bohr model atom corresponds to the atom's period (row) number in the periodic table.
Which part of an atom determines its position as a element on the periodic table?
Because the atom can have the same structure as another atom and those can be together on the periodic table.
The organization of the periodic table is based on what?
The Periodic Table is organized by Atomic Number (the number of protons) and the Electron Shell capacity (the number of electrons).
The periods in the Periodic Table have the same number of what?
They have the same number of electron shells.
How would you find valence electrons in a periodic table?
the group number of the periodic table shows the valence electron. such as :- sodium is placed in group 1 and have valence electron.
Which way does electron shells increase on the periodic table?
The number of shells in periodic table increase down the group, i.e., vertically.
Which number tells you the number of valence electron?
Indirectly this can be derived from the number of the group in the periodic table.
How are the number of electron in the outer level and columns of the periodic table related?
700,000,00,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,
What is the number of valence electron for all the elements in periodic table group 1A 1?
One valence electron.
When is it necessary to start a new period in the periodic table?
Periods in the periodic table represent the number of electron shells necessary to fit all of the electrons. Once you fill the valence shell of an atom, the next electron must go in a new electron shell. This would constitute a new period on the periodic table.
Do elements in the same column of the periodic table have the same number of electron shells?
Yes
What is the number of valence electrons in family 1A of the periodic table?
One valence electron.
How many electron rings are found in each period of the periodic table?
The number of period corresponds to the total number of electron rings.
Why is hydrogen the first element?
As the periodic table is arranged in order of increasing atomic number hydrogen is the first element in the periodic table as it has only one electron.
