What branch of science studies what takes place outside of Earth's atmosphere?
Astronomy.
What is it called when this has mass and volume and it's the "stuff" that all physical objects are made of?
Matter.
Substance made of only one type of atom.
Element
An atom that has an unequal number of electrons and protons.
Ion
An atom that has more or less neutrons.
Isotope
The smallest particle of a compound that still has its properties.
Molecule
Stable gasses that are very unreactive due to the fact they have full sets of their outermost valence electrons.
Noble gasses
A bond where atoms share one or more of their outermost valence electrons.
Covalent bond
The grouping of elements according to their properties developed by Dmitri Mendeleev.
Periodic Table
When substances combine but not in any specific proportions and not chemically
Mixture
A mixture with the same proportion of substances throughout. A mixture where the ingredient are evenly mixed.
Homogeneous mixture
A mixture with different proportions of substances throughout. A mixture where you can see the different parts because they are not evenly mixed.
Heterogeneous mixture
The portion of a mixture that is dissolved in the liquid.
Solute
The liquid portion of a solution in which other substances are dissolved into.
Solvent
Original substances that interact with each other in chemical reactions.
Reactants
What's the difference between homogeneous and heterogeneous mixtures? Give an example.
The difference between homogeneous and heterogeneous mixtures is that a homogenous mixture will have the same composition throughout and a heterogeneous mixture has a different composition throughout. An example of a homogeneous mixture is lemonade. An example of a heterogeneous mixture is a jar of jelly beans.
Reaction in which heat is absorbed? Reaction in which heat is created?
Endothermic Reaction and Exothermic Reaction
How is a substance with high density different than one with low density?
High density substances have their atoms arranged closer together than substances with a lower density.
Why does water have surface tension?
Water molecules are attracted to each other and the weak hydrogen bonds create surface tension.
