Chemistry Mid term Part 1

evenly distributed, but can be physically broken down into different components

the number of digits in a measurement that reflect how accurate the measurement is

a row in the periodic table of elements

when the solute is dissolved in water

one half the distance between the nuclei of two identical atoms bonded together

equal to the number of protons for the atom; used to identify elements on the periodic table

electrons in the outermost energy level of an atom

made of positive and negative ions that chemically combined in a way that the charges cancel out

chemically combined atoms of two or more different elements

atoms of an element with a different number of neutrons

metals that "transition" because they form many different ions

made up of protons and neutrons

a force/mutual attraction that holds atoms together in a substance

have excess nuclear energy and thus are unstable and more likely to decay

negatively charged from gaining electrons (typically nonmetals)

the smallest unit of an element that maintains the identity of the element; building block of matter

typically a solution of two metals mixed together

a 3D region around the nucleus that shows where an electron probably is

a measure of the ability of an atom to attract and hold electrons

the emission of radiation

formed when electrons are transferred from the atom with the lowest electronegativity to the higher

the charge of an ion

specific patterns in the periodic table that make it possible to make predictions about an elements properties

atoms or molecules that have a charge due to having lost or gained electrons

a measure of how much space something takes up

states that it is impossible to determine the position and velocity of an electron or other particles simultaneously

the formation of new elements through nuclear chemistry

uneven distribution; "different"; can be physically broken down into different components often easily

neutral subatomic particle found in the nucleus, responsible for mass

anything that has mass and volume

how long it takes half of an atom to decay

total number of protons and neutrons found in the nucleus of an atom

the number of waves that pass a given point in a certain time

physical combination; variable composition throughout; each component retains its unique properties

one kind of metal bonded to one kind of nonmetal atom
