Unit 1
The properties of a metalloids
What is malleable, solid, ductile, shiny or dull, and conducts heat and electricity?
The subscript
What is a representation of a substance in which the subscripts, and the number of atoms represent the chemical formula of each element?
Net Force
What is the overall forces acting on an object measured in Newtons?
Cold Front
What is a boundary between a cold air mass and a warm air mass?
Valence Electrons
What is an electron in one of the outer shells of an atom?
Unexpected Temperature Change
What is a chemical bonding energy that is released or absorbed making their surroundings hotter or colder?
Newton’s First Law
What is an object in motion that tends to stay in motion with the same speed and direction unless acted on by a unbalanced force?
Warm Front
What is a region where warm air masses is replacing a cold air masses?
Properties of Metals
What is luster, good conductor, high density, ductile, malleable, and high melting point?
Chemical Symbol
What is a letter or pair of letters that represent the element in the formula?
Newton’s Second Law
What is acceleration that is produced when a force acts on a mass?
Stationary Front
What is it when a warm air mass and cold air mass meet, but neither has enough force to move the other?
The number of Neutrons
What is the mass number that is in the nucleus?
Bubbles
What is it when gases produced in a chemical reaction are released?
Newton’s Third Law
What is it when in every action there is an equal and opposite reaction?
Occluded Front
What is it when two cold air masses trap a warm air mass and force it upward?
