GR 10 CHEM NO1 Flashcards
why do atoms bond to form compounds?
atoms are electrically attracted to eachother and they have force of attraction until the chemical bond is formed
aquire stable octet by…
losing, gaining or sharing valence electrons
ionic bonding occurs with
occurs between metals and non meatls
and ionic bond is
force of atraction between oppositley charged ions
ionic compound
a chemical compound composed of ions held together by electrostatic forces termed ionic bonding
the name for K2O
potassim oxide
name for SnCl2
Tin (II) Chloride
polyatomic ions are
a group of atoms that tend to stay together and carry an overall charge together
Ate (polyatomic ion)
ic acid
ite (polyatomic ion)
ous acid
Bianary acid
when H+1 is bonded to a monoaomic ion
usually very simple, 2 or 3 letters
Oxyacid
when H1+ is binded to a polyatomic ion
the complicated looking acids
how can u identify an acid??
see if there is an H (denoting hydrogen) in front of the molecular formula of the compound.
molecular compunds are
made up of neutral molecules rather then oppositley charrged ones
result of chemical bonds between non metal atoms
non metal + non metal
they are sharerers
WHAT ARE THE DIATOMIC ELEMENTS????!!!!> AND WHAT KINDA BOND AER HEY
H O F Br I N Cl AND MOLECULAR
naming molecular compunds
use PREFIXES to indecate how many of each atom are present
1 mono
2 di
3 tri
4 tetra
5 penta
NH3 is
ammonia
h2o2 is
hydrogen peroxide
ch4 is
methane
03 is
trioxide
h2s
hyrdrogen sulfide (LIDWALLY WHAT)
word equations
hydrogen + oxygen ->
= water ->
a way to represent chemical change
reactants
products
law of conserving mass (protecting from harm - mass)
that total mass of reactants before the chemical change = o the total mass of the products formed apres le chemical changer
what are aoms doing in chemical change
rearraging, not destorying or creatied
