Periodic Table
100
The smallest unit of an element that maintains the properties of that element
What is an atom?
100
This particle has a positive charge and is found in the nucleus of the atom
What is a proton ?
100
The atomic number of an element will be the same number as these two particles
What are electrons and protons ?
100
You can find this right above the chemical symbol of the element
What is the atomic number ?
200
Protons and neutrons are located in this part of the atom
What is the nucleus ?
200
This particle has no charge and is found in the nucleus of an atom
What is a neutron ?
200
You will get this, when you do this : Atomic mass (minus ) atomic number
What is the number of neutrons ?
200
An abbreviation for the element name
What is a chemical symbol ?
300
An atom of an element with the SAME number of PROTONS as the other atoms but a DIFFERENT number of neutrons Example: some atoms of hydrogen and boron
What is an isotope?
300
These particles have a negative charge and circle the nucleus in energy level rings
What are electrons ?
300
The arraignment of the number of electrons on each energy level ring is called this
What is the electron configuration?
300
This is found beneath the element name and can rounded to the nearest whole number
What is the atomic mass ?
400
An isotope that is unstable, with a nucleus that changes over time is called this type of atom
What is radioactive ?
400
The electron configuration of an atom
What is 2-8-18-32 ?
400
The number of protons plus the number of neutrons will give you this
What is the atomic mass?
400
By looking at the periodic table, you can determine that this is the electronic configuration of magnesium
What is 2-8-2- ? Why?
500
An atom that gains or loses an electron
What is an ion?
500
The name for the electron that is located on the outermost energy level ring
What is the valence electron ?
500
The electron configuration for an element with the atomic number of 9
What is 2-7 ? Why?
500
If you look at the periodic table you can determine this is the number of neutrons for the element Strontium
