100
This is in the center of the atom
What is the nucleus
100
This is the charge on a proton.
What is positive
100
There are 7 of these on the Periodic table. They go across from left to right.
What are periods.
100
This is the definition of a cation.
What is a positively charged ion that has lost electrons.
100
These are the first group. They have 1 valence electron.
What is alkali metals.
200
According to the modern model, these are found in a "cloud"
What is an electron
200
This is the charge on an electron.
What is negative.
200
There are 18 of these on the periodic table. They are vertical columns.
What are groups/families.
200
This is the definition of an anion.
What is a negatively charged ion that has gained electrons.
200
This group's valence electrons vary depending on the element, but they usually give up either electrons.
What is transition metals
300
These two things are represented by the atomic number
What are the protons and electrons
300
There are more of these added to the nucleus of an isotope of an element.
What are neutrons.
300
These tell us how many valence electrons there are for all elements in that particular column.
What are group numbers
300
This group will not have a charge because they have a full octet.
What is the noble gases.
300
This group has 7 valence electrons, making them very reactive.
What is halogens.
400
These two things are represented by the atomic mass number.
What are the protons and neutrons
400
This particle has no charge.
What is a neutron.
400
When going across the periodic table from left to right, this increases by 1 every time you move from one element to another.
What is the atomic number.
400
The alkali metals will easily give up an electron, ending with this charge.
What is +1
400
This family has characteristics of both metals and nonmetals.
What are metalloids.
500
This is the equation used to find the number of just neutrons within the nucleus.
What is the ATOMIC NUMBER - ATOMIC MASS = NEUTRONS
500
These two particles must be equal in order to have a neutral atom.
What are the protons and electrons.
500
Organization of the periodic table is based on this.
What is the number of protons in an atom.
500
The charge on this group could be positive or negative, depending on if it is a metal or nonmetal.
What is group 4
500
This group of elements will gain electrons easily and are located on the right side of the periodic table.
What are nonmetals
