Answer:
They are spherical and hollow (not compact or dense)
Explanation:
An elastic collision is a form of a collision where kinetic energy and momentum are conserved in the process. When there is zero loss of kinetic energy and momentum, it is called a perfectly elastic collision.
This form of collision is observed in atmospheric gases and colliding balls which happens to be spherical and hollow.

dimension like space (height, width, depth). Einstein said it took 4
dimensions (numbers) to define a physical event. 1 for WHEN it happened,

Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, and is the primary interaction occurring in ionic compounds.A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
