100
An uncharged particle that is part of almost every atomic nucleus.
What is a neutron?
100
A system for organizing the elements into columns and rows, so that elements with similar properties are in the same column.
What is the periodic table.
100
Matter that contains only one kind of particle.
What is a pure substance?
100
These groups are very reactive.
What is group 1 and 17?
100
A positively or negatively charged atom or molecule.
What is an ion?
200
A negatively charged particle within the atom.
What is an electron?
200
The average mass of the naturally occurring isotopes of an element. (calculated by mass of protons plus mass of neutrons)
What is the atomic mass?
200
An element in a drink can.
What is an aluminum?
200
This increases from down a group and across a period, from right to left, in the periodic table.
What is an atomic size?
200
A chemical link between two atoms, which holds the atoms together.
What is a chemical bond?
300
In chemistry, the positively charged center of an atom.
What is the nucleus?
300
Typically, an element that is hard, shiny, malleable, and ductile, and is a good conductor of heat and electricity.
What is a metal?
300
Matter that contains more than one kind of particle.
What is a mixture?
300
This increases as you move down a group.
What is a size of an atom?
300
Ions with more than one combining capacity (possible charges) need to have this in order to name it correctly
What are roman numerals?
400
The smallest particle of an element that retains the identity of the element.
What is an atom?
400
Typically, an element that is not shiny, malleable, or ductile, and is a poor conductor of heat and electricity.
What is a non-metal?
400
This is a compound is formed when Na ions combine with Cl ions
What is a NaCl, or salt?
400
An electron in the outermost occupied energy level of an atom.
What is a valence electron?
400
A chemical bond that forms between oppositely charged ions.
What is an ionic bond?
500
A particle that is smaller than the atom.
What is the subatomic particle?
500
A vertical column of elements in the periodic table.
What is a group?
500
This theory states that particles attract each other.
What is the particle theory of matter?
500
These are non reactive because they have a full set of valence electrons.
What is are noble gases?
500
A compound made of oppositely charged ions.
