What is a chemical change?
Salt water
What is homogeneous mixture?
These are charged particles that form when atoms gain or lose electrons
What are ions?
This particle determines the reactivity of the atom
What is the electron?
The ability to burn
What is flammability?
volume
What is a physical property?
What is an element?
Atoms of the same element with differing numbers of neutrons like Carbon-12 and Carbon-14
What are isotopes?
These determine the identity of the element
What are protons?
The ability to dissolve
What is solubility?
Abrasion and other forms of mechanical weathering
What is a physical change?
Water
What is a compound?
This is the weighted average of the masses of all isotopes of an atom
What is atomic mass?
These particles stabilize the nucleus
What are neutrons?
Vaporization is the change of a liquid to this
What is a gas?
Helium is non-reactive
What is a chemical property?
Muddy water
What is a heterogenous mixture?
+ charged ions
What are cations?
In atoms, there are the same number of these two particles and therefore all atoms are electrically neutral (have no charge)
What are protons and electrons??
Matter made up of only 1 type of substance
What is a pure substance?
Odor
What is a physical property?
Air
What is a homogenous mixture?
The number of electrons in the outermost shell
The mass number is determined by adding up these 2 particles
What are protons and neutrons?
Electrons are found here
What is the electron cloud?
