(s)(l)(g)(aq) + random stuff Flashcards
(s)
the compound is a solid
(l)
the compound is a liquid
(g)
the compound is a gas
(aq)
stands for aqueous, and is when a solute is dissolved in the water.
ex: hydrochloric acid is an aqueous solution because it’s dissolved in water
element definition
a substance made of only one type of atom
compound definition
a substance made of 2 or more elements chemically bonded
mixture definition
a substance made of 2 or more elements not chemically bonded
what is the atomic number
the atomic number tells us how many protons and electrons are in an atom/element
what is the atomic mass
the atomic mass tells us how many neutrons and protons are in an atom/element
what are isotopes
atoms of the same element with different mass numbers. they have the same number of protons, but a different number of neutrons
what do particle diagrams for elements look like
they are the same colour and the same size
what do particle diagrams for compounds look like
they show more than 1 type of atom chemically bonded together, and we can tell that it’s made out of more than 1 type of atom because they will be different colours and sizes. we can tell they’re chemically bonded together because they would be joined together.
what do particle diagrams for mixtures look like
2 or more atoms with different colours/ sizes not joined together
