Why should Chemistry be studied in A+P class?
Body functions depend on Cellular functions.
Anything that takes up space and has weight; composed of elements.
Composed of chemically identical atoms
These type of elements are required by the body in large amounts.
These type of elements are required by the body in small amounts.
These types of elements are toxic to the body in large amounts
Smallest particle of an element
Part of an atom that carries a single positive charge
Part of an atom that carries no electrical charge
Part of an atom that carries a single negative charge. They revolve around the nucleus.
Term for the number of protons n the nucleus of one atom and equals the number of electrons...
The number of protons plus the number of neutrons of the atom.
Is it a different element if the number of protons change?
Is it a different element if the number of neutrons change?
No, but it becomes an isotope.
How do you find the neutron number?
Atomic weight minus the atomic number.
Atoms with the same atomic numbers but with different atomic weights are called?
Isotopes. They have the same number of protons and electrons but a different number of neutrons.
This type of radiation is composed of 2 protons and 2 neutrons.
This type of radiation is composed of fast moving electrons.
This type of radiation is composed of electromagnetic wave energy
