CSET Subtest 2 CR's Exam Questions and answers with verified Answers
(Latest Update 2026) UPDATE!!
density - (answer)The amount of "stuff" you have in a certain amount of space. Dens=mass/volume
Conservation of matter - (answer)Matter cannot be destroyed. I.e. the ash and the gas left from log
being burned really adds up to the original mass of the log
element - (answer)Substance that can't be separated into simpler substances by chemical means
atom - (answer)Smallest unit of an element that still has properties of that element. An atom has a
proton, neutron, and electron
proton - (answer)-positive
-located in nucleus
-mass is 1 atomic mass unit (AMU)
neutron - (answer)-neutral
-located in nucleus
-mass is 1 AMU
electron - (answer)-negative
-orbits outside nucleus
-mass is 1/1836th AMU (extremely small)
Balanced atom - (answer)Has the same number of protons and electrons

(Latest Update 2026) UPDATE!!
Imbalanced charge/Ion - (answer)Called an ion. It is positive or negative because of more or less
electrons than protons. A way to remember this is that "ion" is a small word and electrons are a small
particle
isotope - (answer)An atom with a different number of neutrons
Atomic mass - (answer)The amount of matter that makes up an atom. Found by adding up the number
of protons and neutrons
Atomic number - (answer)Number of protons that the atom has
Half life - (answer)The time it takes for half the atom to disintegrate. C14 (carbon 14) can be used to
date organisms that died less than 50,000 years ago
Periodic table - (answer)-atomic number and mass increase as you move left to right and top to bottom
-chemical properties are organized by column--that go up and down
Compound - (answer)Substance composed of two or more elements. I.e. h2o co2, and NaCl
bonds - (answer)What holds atoms together in a compound
-ionic: one atom loses an electron to form a positive ion, and the other gains an electron to form a
negative ion (it's like one atom is chasing the other atom around because it stole the electron from it--
this is how it stays together)
-covalent: atoms share one or more of their electrons (both atoms wont let go of their electron so it
stays attached)
