inorganic chemistry 2

law of conservation of energy/matter

mass can neither be destriyed or created on transformed or transferered

chemical bonding

allows you to link atoms together to create new compounds or molecules

Bonding..

neither destroys nor creates new matter

Types of bonds

ionic, covalent, hydrogen

ionic bonds

involve the attraction of opposite electrical charges

importance of ionic bonds

allows for nerve impulse conduction, musce contraction, fluid balance to happen

ions are?

atoms that have an electrical charge

cohesion

water molecules that stick together ( water droplets)

adhesion

water molecules stick to other surfaces (water moving through plants )

an atoms becomes ?

an postive charged ion when it either gains or loses electrons

positive charged ions are called?

cations

atoms that gain electrons ?

become negatively charged

negatively charged ions are called?

anions

cations and anions that dissolve in water are called?

electrolytes

covalent bonds

form between two atoms when they share pairs of electrons

covalent bonds can be ?

neither polar or non polar

non polar

equal sharing of e- pairs

polar

unequal sharing of e- pairs

hydrogen bonds

are
weak interactions
that form between
two polar covalent
molecules

Water can?

dissolve ionic
compounds by forming
hydrogen bonds with ions
