Define chemistry. a) chemistry is the science of matter and its motion, as well as space and time - the science that deals with concepts such as force, energy, mass, and charge. b) chemistry is the science that seeks to understand what matter does by studying what atoms and molecules do. c) chemistry is the science that studies the molecular transformations only in nonliving matter. d) chemistry is the science that studies the molecular transformations only in living matter.

The correct answer is option B) "Chemistry is the science that seeks to understand what matter does by studying what atoms and molecules do".

Explanation:

Chemistry is a branch of science that deals with the study of matter, the properties that defines it and how it interacts with other matter and energy. Basically, chemistry is the science that seeks to understand what matter does by studying what atoms and molecules do. The basic premise of chemistry is that by dissecting matter and studying its components, we will be able to understand how it behaves and the reactions we see in nature.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
