What information the subatomic particles is given by the element's atomic number?

Answer 1

An element's atomic number gives us the number of electrons surrounding the nucleus of an unionized atom of that element. It also tells us the number of protons in the nucleus of the atom.

6c is a carbon atom 6 in subscript is it's atomic number. it tells us that carbon atom has 6 electrons and 6 protons.

If mass number is given we can find number of neutrons in nucleus also.

no. of neutrons = mass number - atomic number.

6c12 , here 12 in superscript is mass number.

no. of neutrons=12 - 6 = 6 (by using above formula.

Also a knowledge of atomic number helps us determine the arrangement of electrons around the nucleus. Arrangement of electrons determines chemical properties of an element.

Carbon's atom has 2 electron in K(first) shell and 4 electron in L (2nd) shell and thus to have octet(stable configuration) forms four covalent bonds and shows tetra valency.

Mass number and atomic number give us n/p (neutron/proton) ratio which determines stability of nucleus and radioactivity. If an element is radioactive it's atom's nucleus will emit subatomic particles to gain stability.

Answer 2

The atomic number gives you the number of electrons and protons there are in an atom.

Ex: Carbon (C) has atomic number 6. So we know that it has 6 protons and 6 electrons.

Answer 3

it's mass - the total number of neutrons and protons in the nucleus of an atom of that element

Answer 4

The atomic number is the number of protons in the nuclei of the atoms of an element. The atomic number is unique to each individual element.

Answer 5

the number of protons in the element

Answer 6

Number of protons
