A mixture of a gaseous element and gaseous compound

A mixture of a gaseous element and gaseous compound

a gaseous compound

a solid element

a mixture of two gaseous compounds

pure substance has

constant composition

physical change is

in the form of a substance

what can be used to separate mixtures into pure compounds

physical changes

distillation

depends on differences in the volatility of the components through vaporization

what two things can pure substances be

Compounds or free elements

what is a compound

Constant Composition that can be broken down into elements by a chemical process

atomic number is

the number of protons always a whole number on the pt

mass number is

protons+ neutrons on bottom of pt box

isotopes

same protons, dif neutrons OR

same element, dif mass

molecules have

covalent bonds

ions r

atoms that have a charge and have transferred electrons

formula unit

combo of ions held together by an electrostatic attraction from the transfer of electrons in an ionic bond

neutral p=e

atom

average mass of all isotopes

Atomic mass

shared electrons

covalent

transferred electrons

ions

valence electrons

electrons in the outermost energy level that determine the behavior of an atom

elements in the same group

form similar compounds, they have the same ending electron configuration they gain or lose same amount l of electrons

ionic compounds

Metal plus nonmetal

covalent compounds

Two more nonmetals

acids

formula starts with H

sign of chemical change?

Color change-Spontaneous

sign of chemical change?

temperature change -Hot or cold

sign of chemical change?

production of gas-Bubbles smoke odor

sign of chemical change?

production of A solid-Crystals, cloudy grainy

butter melting

Physical change

rust

chemical

digestion

chemical

compound

2 or more elements of chemical combined

mixture

two or more substances physically combined

JJ Thompson

conducted the cathode ray tube experiment

electrons decide

Interacts with other atoms and chemical properties

neutrons decide

The isotope identity and mass

law of conservation of matter

mass is neither created nor destroyed in a chemical reaction
