What are compounds?
the bonding together of different elements
True or false, compounds have different properties than the elements
true
What is bonding?
an interaction between atoms in order for all atoms involved to become more stable

What is ionic bonding?
it’s a type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. exchange of electrons occurs
is ionic bonding a strong or weak bond?
fairly strong bond
true or false..salts and minerals are charged particles…
true
true or false….ionic bonding is less common in the body
true
true or false….any atom that gains an electron becomes negative…
true
what is covalent bonding?
sharing of electrons occurs
true or false…covalent bonding occurs most in the body…..
true
true or false….bonds ares stored energy
true
true or false….1 single covalent bond is the easiest to put together and work with
true
A double covalent bond or ATP is what kind of bond?
double bond
true or false..single bonds are easy to break
true
true or false….a triple bond is difficult to break
true
Where do you see covalent bonding?
mostly in the body
ture or false…salt and minerals are ionic…
true
what is polar bonding?
unequal but partial sharing of electrons
what is non-polar bonding?
equal sharing of electrons with no charge
what is electronegativity?
the ability to draw electrons to an atom
true or false…oxygen is the 2nd most element with electronegativity…
true
true or false…fats are non-polar covalent
true
What is the definition of chemistry?
the branch of science that deals with the identification of the substances of which matter is composed
what is the definition of physiology?
the branch of biology that deals with the normal functions of living organisms and their parts
what is the definition of matter?
Matter is anything that takes up space and can be weighed
What is mass?
a coherent, typically large body of matter with no definite shape
what is the atomic theory?
All materials are composed of matter.
What is atomic structure?
the composition of an atom, which consists of a tiny, positively charged nucleus at the center surrounded by negatively charged electrons orbiting in shells around it
what is an element?
A substance that cannot be broken down into simpler substances by chemical means
what are the elements of life?
The elements of life are primarily considered to be carbon (C), hydrogen (H), oxygen (O), and nitrogen (N) with sulfur (S) and phosphorus (P) (SPONCH collectively)
What is a subatomic particle?
a particle that is smaller than an atom and is a fundamental unit of matter or energy
what does atomic terminology refer to?
it refers to the vocabulary used to describe the structure and components of an atom
what is the definition of a compound?
a substance made up of two or more different elements that are chemically joined together in a fixed ratio
what is the definition of bonding?
refers to the attractive force between atoms that allows them to stick together and form molecules
