Atoms whose symbols appear on a single row of a Periodic Table have the same number of electron shells. (Atoms with different numbers of protons represent different elements.)
There amount of protons, neutron's , and electrons, the smallest amount is 1 and so on.
Atomic Number (amount of protons)
In an atom of an element, the amount of protons in that atom equal the amount of electrons in the atom, but only if it is a neutral atom. That then eqals the atomic number of that element.
Boron atoms have 5 protons. You can derive this from the periodic table because the atomic number is the amount of protons the nucleus of an atom contains.
It tells the amount of protons neutrons and electrons are in an atom.
There amount of protons, neutron's , and electrons, the smallest amount is 1 and so on.
all elements have the same amount of protons and neutrons. when they are not balanced e.g. there is an extra electron, they are no longer atoms they are ions.

Atomic Number (amount of protons)
In an atom of an element, the amount of protons in that atom equal the amount of electrons in the atom, but only if it is a neutral atom. That then eqals the atomic number of that element.
When the number of protons is different another atom exist; the number of protons is specific for only one element.
Boron atoms have 5 protons. You can derive this from the periodic table because the atomic number is the amount of protons the nucleus of an atom contains.
The atomic number is the amount of protons in an element. The number of protons completely determine what element an atom is.
It tells the amount of protons neutrons and electrons are in an atom.
atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number
Sodium, symbol Na, has an atomic number and is number eleven on the periodic table of elements. Therefore, sodium has eleven protons.
the dot method- witch is the electron arrangement is Na-11 Br-35 the amount of protons- the amount of electrons!!] hope that helps :p by- BabeeyJ x
