What charge is a Proton
Positive Charge
Positive Charge represents
Protons
What charge is a Electron
Negative Charge
Negative Charge Represents
Electrons
What charge is a Neutron
Uncharged - Neutral
Uncharged - Neutral Represents
Neutron
What does the Atomic Number represent
Number of protons
Number of protons represents
The Atomic Number
How many naturally occurring elements are there
92
What is Atomic Mass
The mass of an Atom relative to that of an Atom of Carbon which is defined as twelve
The mass of an Atom relative to that of an Atom of Carbon which is defined as twelve represents
Atomic Mass
How do we calculate Atomic Mass
Protons + Neutrons.
Protons + Neutrons is the calculation for
Atomic Mass
What are Isotopes
They are elements which have the same number of Protons but different numbers of neutrons
Elements which have the same number of Protons but different numbers of neutrons are known as
Isotopes
What is Quantum Theory of Energy
Electrons that are limited to certain energy levels
Electrons that are limited to certain energy levels is know as
Quantum Theory of Energy
What are the principal Quantum numbers of shells.
1-7
What is the theoretical number of electrons in any shell
2n2
What is the calculation for electrons in an energy level
Energy level x 2 (Max No. of electrons) Squared (times by itself)
Energy level x 2 (Max No. of electrons) Squared (times by itself) id the calculation for
calculating the number of electrons in an energy level
