What are the most Carbon, Hydrogen, Oxygen, Nitrogen
abundant elements of
the human body?
90% of the human body Carbon, Hydrogen, Oxygen, Nitrogen
is composed of just four
elements which are:
The smallest unit of an Atom
element that still retains
the chemical and
physical properties of
the element is called:
, Protons (positive), Neutrons (neutral) and Electrons
Subatomic particles are:
(negative)
All matter is composed Elements
of basic substances
called
An atom that tells you Atomic Number
how many protons an
atom has is called:
The number of protons Mass Number
and neutrons is called:
The same element but different number in protons
and neutrons-Mass Number (protons plus
What is isotope?
neutrons) minus Atomic Number (number of
protons) equals the number of neutrons.
What is radioactive Atom whose nucleus undergoes degeneration and
isotope? in the process gives off radiation
What is a molecule? Atoms bonded together to form a chemical unit
What is a compound? Combining different atoms
What is ionic bond? Ions with opposite charges attract
Particle that is electrically charged because it has
What are ions?
gained or lost one or more eletrons
What is a covalent Atoms sharing electrons instead of losing or gain
bonds? them
Bond created when electrons shared by adjacent
What is polar bond?
atoms are shared unequally
hydrophilic means water-living
,Hydrophobic means water-fearing
What is electrolyte? Substances that release ions when puts into water
What is pH? a measure of hydrogen ion concentration
Anterior position a body part is located towards the front (ventral)
Posterior position a body part is located toward the back. (dorsal)
a body part is located ABOVE another part or
Superior position
towards the head

A sagittal plane (median) right down the middle
cuts the body
A frontal plane (coronal) from ear to ear, from shoulder to shoulder across
