Atomic Structure and Bonding
This subatomic particle has a positive charge and is found in the nucleas.
What is a proton?
Elements in the same vertical column on the periodic table belong to the same what?
What is a group?
This is the starting material in a chemical reactions.
What is a reactant?
This is the Sl unit for the amount of a substance that is short for mol
What is a mole?
In this state of matter, particles are tightly packed in a fixed argument.
What is a solid?
The number of protons in an atom defines this.
What is the atomic number?
This is the name for elements in group 18 of the periodic table, known for being unreactive.
This is a substance that speeds up a chemical reaction without being consumed.
What is a catalyst?
This is the mass of one mole of a substance, expressed in grams per mol.
What is molar mass?
This is the process of a solid changing directly into a gas.
What is sublimation?
This type of bond forms when electrons are shared between atoms.
What is a covalent bond?
This trend on the periodic table generally increases as you move from left to right across a period.
What is electronegativity?
This type of reaction involves the reaction of a substance with oxygen, often producing heat and light.
What is combustion?
This is the amount of product formed in a chemical reaction.
What is the yield?
In this state of matter, particles are far apart and move randomly, filling the entire volume of their container.
What is a gas?
This is the attractive force between oppositely charged ions in a ionic compund.
What is an Ionic bond?
These are the elements found in groups 3-12 and are technical good conductors of heat and electricity.
What are transition metals?
This law states that matter cannot be created or destroyed in a chemical reaction.
What is the law of conservation of mass?
This is the reactant that is completely confused first in a chemical reaction, determining the maximum amount of product.
What is the limiting reactant?
This is the process where a liquid turns into gas at its surface, even below its boiling point.
What is its evaporation?
This reffers to the region around the nucleus when an electron is likely to be found.
What is an orbital?
This is the name given to the elements in groups 1 and 2 of the periodic table, known for their reactivity.
What are alkaline and alkaline earth metals?
This is a chemical equation that has the same number of atoms of each element on both sides.
What is a balanced chemical reaction?
This is the ratio of the actual yield to the theoretical yield, expressed as a percentage.
What is the percent yield?
This is the temperature and pressure at which all three states of matter can coexist in equilibrium.
What is the triple point?
