Parts of an Atom
These subatomic particles are positively charged
What is a Proton
This determines the number of protons and electrons in the nucleus
What is atomic number?
Give me the electron configuration for hydrogen
1s1
What makes an atom have a neutral charge or 0?
equal number of protons and neutrons
This element is mostly used in batteries
Lithium (Li)
This principal states that electrons must fill the lowest energy sublevel first before moving to the next energy level
What is Aufbau Principal
These subatomic particles are negatively charged
What are electrons
This number is the protons and neutrons in the nucleus
what is the mass number
What is the electron configuration for oxygen?
1s22s22p4
What makes an element and positively charged ion
Taking away electrons
This element would make you rich with a mass of 197
gold (Au)
These subatomic particles have no charge
what are neutrons
This is the formula to calculate the number of neutrons in the nucleus.
Mass Number-atomic number
Mass number subtract the atomic number

what makes an element a negatively charged ion
adding electrons
This element is used in pools
chlorine (Cl)
These subatomic particles are the smallest of the three
electrons
These elements are created when you add neutrons to the nucleus
