CSET MULTIPLE SUBJECTS SUBTEST II E FINAL PAPER EXAM QUESTIONS ACCURATE
ANSWERS FULL SOLUTION
Question:
Isotope.
Answer:
If Atom has different # of Neutrons than its normal amount.
Question:
Atomic Mass.
Answer:
The amount of matter that makes up an Atom
Question:
Atomic #.
Answer:
The # of Protons an Atom has.
Question:
Radioactive Decay.
Answer:
Most Isotopes decay back into their normal forms over time. The time required for 1/2 the atoms of
a particular substance to disintegrate is known as that substance's "Half-Life," or 5400 years. The
rate of decay slows down after 5400 years.
,Question:
Periodic Table.
Answer:
Atomic Properties: Organized by Rows Atomic # increases as you go RIGHT/DOWN. Chemical
Properties: Loosely arranged in columns.
Question:
Compound.
Answer:
Two or more elements combined
Question:
Bond.
Answer:
Within Compounds, the Atoms that make up molecules, are held together by Bonds (The glue that
holds them together- like "Denture Bond). Two Types: Ionic: 1 Atom loses an electron to form a +
Ion, the other gains electron to form - Ion, creating electrostatic force which holds them together (
Chasing to get it back) Covalent: Bond formed when Atoms share 1 + electrons (when both won't let
go).
Question:
Chemical Change.
Answer:
Chemical composition is altered.
Question:
Catalyst.
Answer:
, Something that starts a chemical reaction
Question:
Mixture.
Answer:
Material that can be separated by physical means into 2+ substances.
Question:
Solution.
Answer:
Homogeneous mixture which 1 solution dissolves into another.
Question:
Suspension.
Answer:
Small particles are kept dispersed by agitation/molecular motion in surrounding medium. Ex.
Muddy water in river. In river= mixed. NOt moving (agitations) = separated.
Question:
Physical Changes.
Answer:
Solid: Cannot be compressed or take shape of a container Liquid: Yes Gas: Yes *The more pressure
there is on something= the more it will want to be a solid. The less pressure= the more it will want to
be a gas.
Question:
Boyle's Law.
