B
This subatomic particle has a positive charge and is found in the nucleus.
What is a proton?
This negatively charged subatomic particle moves around the nucleus in energy levels.
What is an electron?
This neutral particle is found in the nucleus and has a mass of about 1 amu.
What is a neutron?
This is the center of the atom that contains protons and neutrons.
What is the nucleus?
An atom that gains electrons becomes this type of ion.
What is an anion?
An atom that loses electrons becomes this type of ion.
What is a cation?
This rule states that atoms tend to want 8 electrons in their outermost energy level.
What is the Octet Rule?
These electrons are found in the outermost energy level and determine bonding behavior.
What are valence electrons?
This type of diagram uses dots around an element symbol to show valence electrons.
What is a Lewis Dot Structure?
This pure substance is made of only one kind of atom.
What is an element?
This pure substance is made of two or more different elements chemically bonded together.
What is a compound?
This is a combination of substances that are not chemically bonded and can be physically separated.
What is a mixture?
Atoms of the same element with different numbers of neutrons are called these.
What are isotopes?
This value equals the number of protons plus neutrons in the nucleus.
What is the mass number?
The number of protons in an atom determines this property of the element.
What is the atomic number?
This property changes depending on how much matter is present, such as mass or volume.
What is an extensive property?
This type of property does not depend on the amount of substance present, such as color or boiling point.
What is an intensive property?
According to the notes, high frequency light has this type of wavelength.
What is a short wavelength?
When electrons fall back to lower energy levels, they release energy in the form of this.
What is light?
This term describes the regions around the nucleus where electrons are likely to be found.
What are energy levels?
This effect explains why electrons farther from the nucleus are easier to remove.
What is the shielding effect?
The average atomic mass of an element is calculated using this type of average.
What is a weighted average?
The electron configuration 1s² 2s² 2p⁴ belongs to this element.
What is oxygen?
This equation relates the energy of light waves to frequency.
What is E = hf?
This scientist discovered that energy is quantized and related energy to frequency.
Who is Max Planck?
