What are the three main subatomic particles of an atom?
Protons, neutrons, and electrons.
What is the charge of a proton?
1+
What is the Charge of a neutron?
0
What is the charge of an electron?
-1
Where are Protons located?
nucleus
Where are Neutrons located?
Nucleus
Where are electrons located?
outside the nucleus
Why does an atom in the elemental state always have a neutral charge?
The number of protons equals the number of electrons
what are electrons in the lowest available energy level said to be?
ground state
what does it mean when an atom is said to be in an excited state?
The excited state is when an atom absorbs energy , and its electrons move to a higher energy level.
Isotopes
atoms of one element that vary only in number of neutrons in the nucleus.
Why are all isotopes of the same element identical, chemically?
they have the same number of electrons
radioisotopes
emit particles and decay at a known rate called a half-life.
When is a atomic bond formed?
when two atomic nuclei attract the same number of electrons.
Ionic bonds
form when electrons are transferred.
