Atomic radius depends upon
(A) Number of bonds formed by the
atom
(B) nature of the bonding
(C) Oxidation state of the atom
(D) All the above
Answers
Answer:
The answer is all the above
Answer:
B) nature of bonding
Step-by-step explanation:
The atomic radius of a chemical element is a measure of the size of its atom, usually the mean or typical distance from the center of the nucleus to the outermost isolated electron. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius.
The value of atomic radii depends on the type of chemical bond in which the atoms are involved (metallic, ionic, or covalent bond). When the neighbouring atoms are not alike, as in sodium chloride, part of the observed distance between atoms is assigned to one kind of atom and the rest to the other kind.
What Affects the Atomic Radius?
- Atomic Structure. An atom is made up of a central nucleus of protons and neutrons surrounded by a cloud of electrons.
- Atomic Number. As the atomic number of an element increases, so does the size of its nucleus and the number of electrons around it.
- Periodic Table Row.
- Electron Energy.
In general, atomic radius reduces as one progresses through a period and increases as one progresses through a group. The number of energy levels (n) grows as one moves down a group, resulting in a greater distance between the nucleus and the outermost orbital. As a result, the atomic radius increases.
