The Basics
The charge-less particle in the nucleus.
What is the neutron?
How many electrons fit into any individual orbital space?
What is two (2) electrons?
Each box of the periodic table represents a different one of these.
What is an element?
The most common type of element found on the periodic table.
What are metals?
The atomic radius (size) of an atom changes in this manner as you move up and right on the periodic table.
What is decreases?
The smallest subatomic particle (negatively charged).
What is an electron?
The lowest energy state of electrons in the atom.
What is the ground state?
The boxes on the periodic table are organized based on this number.
What is the atomic number?
These are the least common type of elements found on the periodic table.
What are metalloids (or semi-metals)?
These two properties of the elements (trends discussed in class) increase as you move right on the periodic table.
What are ionization energy and electronegativity?
This is the sum of the protons and neutrons.
What is the mass number?
These are the electrons in the highest energy level of any atom.
What are valence electrons?
This is what we call each row and column on the periodic table.
What are periods and groups?
If you change this about an atom you change the element.
What is the number of protons (or atomic number)?
Positively charged atoms result from this change in the atom.
What is losing one or more electrons?
Changing the number of this particle in an atom does not alter the element's identity nor its charge.
What is the neutron?
The possible sublevels of electron arrangement in energy level 4 in order by increasing energy.
What are s, p, d, f?
Some, but not all, groups are also called this.
What are families?
The element with 6 electrons in its neutral state.
What is carbon?
Noble gases do not exhibit a value in this trend.
What is electronegativity?
In a neutral atom, these are always equal in an atom.
What are protons and electrons?
The maximum number of electrons that fit in the first three energy levels together.
What is twenty-eight (28) electrons?
This is the reason behind the gaps in the first three rows of the periodic table as well as the deciding factor for where a new period starts and ends and the total number of groups.
What is the electron arrangement?
This family of elements represents the most stable elements in the universe.
What are noble gases?
The expected change in atomic radii (size) from a neutral atom to an ionic atom if the original atom has a high electronegativity and high ionization energy.
What is an increase in atomic radii (size)?
