Chapter 2 - The Chemical Context of Life

________ study life, yet organisms and their environs are natural systems to which chemistry and physics ideas apply.

________ have created more than 100 types of particles from the atom via high- energy collisions, but only three types of particles are important here: neutrons, protons, and electrons.

________, for example, is sodium chloride (NaCl), a chemical formed in a 1: 1 ratio of the elements sodium (Na) and chlorine (Cl)

________ and protons are both electrically charged.

Nature, unlike ________, is not cleanly divided into distinct sciences- biology, chemistry, physics, and so on.

For many ant species, the ________ is presumably used as a disinfectant to protect the ants from microbial parasites rather than being fired out.

________ is an interdisciplinary field.

Consuming ________ or iodized salt lowers the risk of goiter.

A compound is a material made up of two or more distinct components mixed in a(n) ________.

________ live in colonies of hundreds or thousands, and the colony as a whole possesses a very efficient defense mechanism.

________ and neutrons are densely packed together in a compact core, or atomic nucleus, in the heart of an atom; ________ provide the nucleus with positivity.

As the ________ interacts with the toxic gas chlorine to produce the edible compound sodium chloride or table salt, the emerging characteristics of the combination can be discovered.

________ occurs naturally in various parts of the world and can enter groundwater.

A(n) ________ is a material that can not be broken down chemically into other compounds.

The ________ elements refer to being required by an organism in only minute quantities.

Although the atom is the smallest unit with elemental characteristics, these ________ are made up of even smaller components known as subatomic particles.

________ is generated by numerous ant species and derives its name from the Latin word for ant, Formica.
