pls mark me as brainliest

Answer 2

Answer:

The correct answer is option (A) Sc > Ti > V > Cr.

Explanation:

• Atomic radius, also known as atomic radius, is the total distance between an atom's nucleus and its electron's outermost orbital.
• The atomic radius of a chemical element is defined as: The average or normal distance between the nucleus's centre and the boundary of the surrounding electron shells.
• The atomic radius of a neutral atom is half of its diameter. In other words, it measures half the diameter of the atom in the outermost stable electrons.
• The ionic radius is equal to half the distance between two gas atoms in contact.
• Only by measuring the distance between the nuclei of two contacting atoms and then halving that distance can the radius of an atom be determined.
