relation between increasing atomic number changes atomic radius

Ratio is the numerical relation of one quantity to another of the same kind. To find the ratio of 2 m 25 cm to 75 cm, we first change 2 m 25 cm into cm, which equals 225 cm. Now, we have to find 225 cm to 75 cm ratio is = 3 : 1 We can write the above ratio as (i) 3 : 1 or (ii) o..

The distance from the centre of the nucleus to the outermost shell of an atom is called the atomic radius of that atom. Electrons in the same period progressively increase from left to right, as the atomic number increa..

While studying the periodic table, it will be noticed that with the increase in the atomic number, there is an increase in atomic mass as well (with some exceptions). Usually an element with high atomic number has high ..

;). For Balmer series, n 1 = 2, n 2 = 3,4,5,… For Paschen series, n 1 =3, n 2 = 4,5,6… For Brackett series, n 1 = 4, n 2 = 5,6,7…. For P fund series, n 1 = 5, n 2 = 6,7,8…. Total energy of an electron in a stationary orbit is calculated from the relation A..

>The mass of electrons is negligible compared to the mass of the protons. Ordinary hydrogen is the only element that has no neutron in it. According to Bohr electrons revolve around the nucleus in fixed orbits called K, L, M, N etc. The energy of the shells increases as the distance form ..

Atom was derived from the Greek word 'atoms', meaning 'indivisible'. Thus, it was considered to be indivisible.Atoms of the same element are identical in shape, size, mass and other properties.Atoms cannot be created, divided or destroyed during any che..

Atom is the smallest particle of an element, which may or may not have independent existence. It is made up of subatomic particles like electrons, protons and neutrons. Atoms of one type of element differ from those of the other due to different number of subatomic pa..
