Atomic Structure
This subatomic particle has a positive charge and is found in the nucleus.
What is a proton?
A chemical change in which a substance reacts with oxygen.
What is oxidation?
The horizontal rows of the periodic table are called these.
What are periods?
This state of matter has a definite shape and definite volume.
What is a solid?
A substance with a pH greater than 7.
What is a base?
The total number of protons and neutrons in an atom.
What is the mass number?
This law states that matter is neither created nor destroyed in a chemical reaction.
What is the Law of Conservation of Mass?
Elements in the same column share this in common.
What are similar chemical properties?
The phase change from liquid to gas.
What is evaporation or vaporization?
This scale measures how acidic or basic a solution is.
What is the pH scale?
This subatomic particle has no charge.
What is a neutron?
A reaction in which energy is released to the surroundings.
What is an exothermic reaction?
This group of elements is known for being highly reactive metals.
What are alkali metals?
This state of matter has particles that move freely and fill their container.
What is a gas?
According to Arrhenius, acids produce this ion in water.
What is the hydrogen ion (H⁺)?
Atoms of the same element with different numbers of neutrons are called these.
What are isotopes?
This type of reaction occurs when two compounds exchange ions.
What is a double replacement reaction?
This trend describes an atom’s ability to attract electrons in a bond.
What is electronegativity?
The change from a gas directly to a solid.
What is deposition?
A solution that can dissolve more solute at a given temperature is described as this.
What is unsaturated?
This model of the atom shows electrons in specific energy levels around the nucleus.
What is the Bohr model?
This type of chemical reaction occurs when a substance reacts with oxygen to produce carbon dioxide and water, releasing energy.
What is a combustion reaction?
The element with atomic number 8.
What is oxygen?
The energy required to change a substance from solid to liquid without changing temperature.
What is the heat of fusion?
This process evenly distributes solute particles throughout a solution.
What is dissolution?
