Matter
This state of matter has a definite shape and volume because its molecules are tightly packed together.
A solid
This is determined by the number of protons an element has.
This is created when two or more nonmetals share electrons.
Covalent bond
This property is the attraction of molecules of the same kind to each other.
adhesion
A solution is an example of this type of mixture.
homogenous
A substance that cannot be broken down into other substances by chemical reactions is known as what?
Element
This decreases as one moves down the periodic table.
Electronegativity.
This is created when a nonmetal and metal transfer electrons to each other.
Ionic Bonds
Water striders (a type of insect) can move swiftly across a pond without breaking the water’s surface. This is due to their light weight and the water’s __________.
Surface tension
When NaCl is added to water, the Na+ ions are attracted to this molecule while the Cl- are attracted to this molecule.
Oxygen, hydrogen
These are the four elements that are essential to the survival of a species.
CHON
Elements in the same vertical column have the same number of these.
Valence electrons
This type of covalent bond is created when electrons are shared equally between two atoms.
Nonpolar covalent bond.
The property occurs when adhesion in greater than cohesion in the xylem of plants
Capillary Action
When water is mixed with a substance that dissolves in the water, the water molecules will act as this by resisting changings to pH.
Buffer
A substance consisting of two or more different elements combined in a fix ratio is known as what?
A compound
This is determined by the number of protons and neutrons averaged over all isotopes.
Atomic Mass
This is known as a positively charged ion.
Cation.
This is the name of the substance that is dissolved in water.
Solute
Because Human urine has a pH of 6, the substance is known as this type of substance.
Acidic.
A substance that cannot be broken down into other substances by chemical reactions is known as what?
Trace substances
An isotope of carbon has 6 protons, 7 neutrons, and 6 electrons. Its atomic number is __________ and its mass number is __________.
6; 13
This is created when a partially positive hydrogen atom is attracted to an electronegative atom in a polar covalent molecule.
Hydrogen bond/Intermolecular bond.
This substance releases hydroxide ions when dissolved in water.
bases
Your Uncle Eddie likes to put a lot of sugar in his coffee. When he does so, he is making a __________ in which the coffee is the __________ and the sugar is the __________.
Solution, Solvent, Solute
