Question

which of the following interactions results in a new substance? i. when atoms mix homogeneously ii. when atoms combine by transferring electrons iii. when atoms combine by sharing electrons iv. when atoms mix heterogeneously a. ii and iii only b. ii and iv only c. i and iii only d. i, ii, and iii only

Explanation:

When atoms combine by transferring electrons (ionic bonding) or sharing electrons (covalent bonding), a new substance is formed. Mixing atoms homogeneously or heterogeneously just results in mixtures, not new substances at the chemical - bonding level.

Answer:

A. II and III only
