Phases of matter
The physical forms that matter can take, solid, liquid, gas, and plasma
What are the Phases of matter?
An object in motion stays in motion, and an object at rest stays at rest unless acted on by an unbalanced force.
What is Newton´s 1st Law?
If a metal gives up one electron, what charge will it have?
1+
Smallest part of an element that can still retain the properties of that element
What is a atom?
What element is this H?
Hydrogen
The change of matter from one phase to another. Solid melting to a liquid, or liquid becoming a gas. It always involves a change in energy levels.
What is phase change?
F= mass x acceleration.
What is Newton´s 2nd law equation?
The electrons in the outermost shell
What are valence electrons?
A Danish physicist that proposed that electrons do not move freely, but rather they move in precise steps, now known as energy levels.
Who is Niels Bohr?
What is this element, O
Oxygen.
The phase of a solid turning into a liquid. The energy involved increases.
What is melting?
For every action, there is an equal but opposite reaction.
What is Newton´s 3rd law?
Metals typically __(gain/lose) electrons.
lose
Atoms with the same number of protons but different numbers of neutrons.
What are Isotopes?
What is this element B?
Boron
The phase change of a liquid turning into a solid. The energy involved decreases.
What is freezing?
An acceleration acts on every object on Earth
What is gravity?
Nonmetals typically ___(lose/gain) electrons.
gain
A substance formed by 2 elements.
What are compound elements?
What is this element N?
Nitrogen.
The phase change of liquid turning into a gas by heating. Heating a liquid gives the particles enough energy to change into a gas.
What is vaporization?
A force that works against motion.
What is friction?
The main force driving chemical reactions is an atom´s desire to have ___.
Full electron shells.
What is electron?
What is this element, Be?
Beryllium
