atomic radii vs atomic number

The atomic radii of group 14 elements are smaller than the corresponding elements of group 13. Explanation: This is because as one moves from group 13 to group 14 elements within the same period, the nuclear charge increases and consequently the size decreases. Within the group..

The atomic and ionic radii of the elements of this group increase on going down the group. This is due to the increase in the number of electron shell..

The atomic and ionic radii of alkaline Earth metals are smaller than the corresponding members of the alkali metals. This is due to the fact of Group 2 elements having a higher nuclear charge allow electrons to be attracted more towards the nucleus. This reduces the size of ..

Fig: 4.3 - Calculation of atomic radius The inter-nuclear distance corresponds to the diameter of the atom and therefore half of this distance gives the atomic radius for a homonuclear molecule like Cl-Cl or Br-Br. Hence, it may be defined as one half of the distance b..

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..

The distance from the centre of the nucleus to the outermost shell of an atom is called the atomic radius of that atom (Fig. 2.1..

The atomic and ionic radii of group 13 elements are compared to corresponding elements of group 2. This is due to the increase in nuclear charge when one moves from, element of group 2 to group 13 in the same period. As the elements are considered from left to right in the peri..

Atomic Number and Atomic Mass - The nuclei of atoms is made up of protons and neutrons. These two components of the nucleus are referred to as nucleons. The electrons occupy the space outside the nucleus. Since an atom is electrically neutral, the h..

The nuclei of atoms is made up of protons and neutrons. These two components of the nucleus are referred to as nucleons. The electrons occupy the space outside the nucleus. Since an atom is electrically neutral, the number of protons in the nucleus is exactly equ..

The number of protons or the number of electrons in an atom in its normal state is called the atomic number and is denoted by Z. The nucleus of every element contains Z protons and some number of neutrons. The electrons, having the same ch..
