100
The right side of the periodic table is made up of these types of elements.
What are non-metals?
100
This is the center of an atom.
What is the nucleus?
100
A substance that is made from the atoms of two or more elements that are chemically bonded.
What is a compound?
100
The energy transferred between matter because of their difference in temperature.
What is heat?
100
This represents, with symbols and formulas, the identities and relative amounts of the reactants and products in a chemical reaction.
What is a chemical reaction?
200
Group 7 elements arte called this.
What are halogens?
200
This value determines the identity of an element.
What is an atomic number?
200
A change in which one or more substances are converted into different substances.
What is a chemical change/chemical reaction?
200
The amount of energy required to raise the temperature of one gram of substance by 1 degree Celsius or kelvin.
What is specific heat?
200
A small whole number that appears in front of a formula in a chemical equation.
What is a coefficient?
300
This is the most conductive metal.
What is silver?
300
This cannot be broken by chemical means.
What is an atom?
300
An element that has some characteristics of metals and some characteristics of nonmetals.
What is a metalloid?
300
The SI unit of heat as well as all other forms of energy.
What is a Joule?
300
A substance combines with oxygen, releasing a large amount of energy in the form of light and heat.
What is a combustion reaction?
400
As you go to the right or up groups, this happens.
What is increasing electron negativity?
400
6.02*10^23, the number of particles in one mole of a pure substance.
What is Avogadro's number?
400
Mixtures that are not uniform throughout are this.
What is heterogeneous?
400
The energy absorbed or released as heat into chemical or physical change is measured in one of these.
What is a calorimeter?
400
The ions of two compounds exchange places in an aqueous solution to form two new compounds.
What is double-replacement reaction?
500
This the character of an element that can be defined as readily an atom can lose an electron.
What is metallic trend?
500
Atoms of the same element that have different masses are this.
What are isotopes?
500
A high temperature physical state of matter in which atoms lose their electrons.
What is plasma?
500
The equation used to find specific heat?
What is Q=MC(T)?
500
Sometimes known as a displacement reaction, one element replaces a similar element in a compound.
What is a single-replacement reaction?
