What are the three Subatomic Protons, Neutrons, Electrons
Particles?
What is a proton? Subatomic particle located inside the nucleus with
positive charge.
Why are Protons important? To identify our elements by their atomic numbers.
What is a Neutron? Subatomic particle located inside the nucleus with
Neutral charge
Why are Neutrons important? With Neutrons we can get Atomic Mass.
(Neutrons) What is Atomic Mass? Number of Protons with Neutrons
What are Electrons? Subatomic particle that orbits surrounding the
nucleus with negative charge.
,Why are Electrons important? Based upon the arrangement of Electrons we can
determine how and why one element will interact
with another one.
What happens if you gain an You become more negative
electron?
What happens if you lose an You become more positive
electron?
How many electrons can you put In 1st orbit= 2 electrons, 2nd orbit= 8 electrons 3rd
the 1st, 2nd and 3rd orbit? orbit= 8 electrons
What are the two rules for atoms? Orbits like to be full. Electrons like to be paired.
What are the 4 common elements? Hydrogen, Oxygen, Nitrogen and Carbon
How many unpaired electrons does 1
Hydrogen have?
How many unpaired electrons does 2
Oxygen have?
How many unpaired electrons does 3
Nitrogen have?
How many unpaired electrons does 4
carbon have?
What is an Ionic Bond? Complete transfer of electrons (sodium chloride,
magnesium chloride)
What is a covalent bond? Sharing electrons
, What is a non-polar covalent bond? Equal sharing of electrons
What is a polar covalent bond? Uneven sharing of electrons. (Ex. Water)
Hydrogen bond? Interaction between a negative atoms with
Hydrogen in which that hydrogen is already part of
a polar covalent bond
What are the three parts of "The Cell 1. All organism are composed of one or more cells
Theory" 2.The cell is the smallest unit of life 3.New cells are
formed only by the division of previously existing
cells
The difference between a Prokaryote PROKARYOTES- All uni-cellular, no nucleus,
and Eukaryote? plasma membrane, no cytoskeleton. EUKARYOTE-
Nucleus with a double membrane, several
membrane bound structures.
What is an ACID? Anything that raises hydrogen ion concentration
What is a BASE? Anything that lowers hydrogen ion concentration
PH scale is a? Base 10 scale
