Particle with positive charge
What is proton
——- is a letter or pair of letters that represent the element
What is chemical symbol
Definition of force
Definition of cold front
What is a cold front it is a cold weather front is a boundary between a cold air mass and a warmer air mass.
Particle with a negative charge
What is electron
Example of chemical change
What is burning, unexpected color change, bubbles
Definition of balanced force
What is The object stays still or countinues to move at the same speed And in the same direction
Definition of warm front
What is a warm weather front is a region where a warm air mass is replacing a cold air mass.
What is neutron
Definition of bubbles
What is when Gasses produced in a chemical reaction are released
Diffention of unbalanced force
What is unbalanced force is a force that cause a object to change position or Direction or speed
Definition of stationary front
What is a stationary front is where a warm air mass and a cold air mass meet, but neither has enough force to move the other
M.A.N. Stands for
What is mass number- atomic number = neutrons
Step to counting atoms
What is Step 1: List the elements in the Chemical Formula.
Step 2: Count the number of atoms each element in the formula using the subscript to the right of thechemical symbol.
Step 3: If Parentheses are present multiply the subscript on the outside of the parentheses with the subscripts of each element on the inside of the parentheses.
Step 4: If Coefficients are present, multiply each subscript by the coefficients
Step 5: Add up the number of atoms of each element in the chemical formula = number of atoms in
What is the overall forces acting on an object and is measured in newtons
Definition of occluded front
What is Occluded fronts happen when two cold air masses trap a warm air mass and force it upward.
