Introduction to Matter
Anything that has mass and takes up space
What is matter?
Something that has a definite shape and definite volume.
What is a solid?
A push or pull on a object.
The smallest particle that can still be considered an element.
What is an atom?
The lightest element on the periodic table.
What is Hydrogen?
A characteristic that can be observed without changing the matter into another type of matter.
What is a physical property?
The resistance of flowing in a liquid.
What is viscosity?
When an object's position changes relative to another object.
What is motion?
The negatively charged particles in atoms.
What are electrons?
These are the type of elements found on Group 18 of the periodic table.
What are noble gases?
A group of two or more atoms held together by chemical bonds.
What is a molecule?
The total kinetic and potential energy of all the particles in an object or substance.
What is thermal energy?
The energy that an object possess while being in motion.
What is kinetic energy?
The charge of the dense center called the nucleus in the atom.
What is positive?
The characteristic that all elements in a group have in common.
What are similar chemical properties?
or
What are the same number of valence electrons in their outer shell?
Adding yeast to bread dough creates a...
What is a chemical reaction?
When the surface particles of a solid gain enough energy that they form a gas.
What is sublimation?
The energy associated with objects that can be compressed or stretched.
What is elastic potential energy?
This part of the atom has the highest energy.
What are valence electrons?
The person who organized the elements into the modern periodic table.
Who is Mendeleev?
This law states that matter is neither created nor destroyed.
The law of conservation of mass
The relationship between the pressure and volume of a gas.
What is Boyle's law?
The formula to calculate power.
Power= work/time
or
Power= force x distance/time
Atoms with the same number of protons and different numbers of neutrons.
What are isotopes?
The way atoms are arranged in the modern periodic table.
What is by increasing atomic number?
