intro to chemistry
what is chemistry
study of the composition of matter and the changes it undergoes
what does atomos mean
invisible
how many periods are on the perodic table
7
what are the three types of bonds
ionic,covalent,metalic
what is a acid
a molecular compound that contains hydrogen and produces hydrogen ions when dissolved in water
what is pure chemistry
a greater understanding of the theories behind how matter is changing
what is the law of conversation of mass
in a chemical reaction the mass of the reactants equals the mass of products
what are most of the elements grouped as
transition metals
what is a ionic bond
bond between a metal and a non metal
what is a binary acid
what is applied chemistry
directed toward a specific goal or apllication
what is a ion
a positively or negitily charged atom
how are elements aranged on the perodic table
they are arranged by atomic number
what is a covalent bond
a bond between a nonmetal and a nonmetal
oxy acid
contains hydrogen, oxygen and one other element
what is organic chemistry
chemestry that deals with carbon
what is the charge of a atom
neutral
what group are the alkiline metals in
the first group
what is a metalic bond
a bond between a metal and a metal
if a anion ends in ide it changes to what
you add hydro to the front and change the ending to ic
what is inorganic chemestry
chemistry dealing with this that do not contain chemistry
what makes a certain element that emement
the number of protons a atom has
what is the name of the elements in the 18th group
noble gasses
what is a cation
metals lose a electron and gain a positive charge
if a anoin ends in ate you change it to
-ic
