other atom such as oxygen (O) or
sulfur (S). What, then is a
hydrocarbon?

both atoms that have 'bonded'. How
many types of bonding are there?

Ionic bonds occur when one atom gives up
one or more electrons to another atom
creating a bond. What happens during covalent
bonding?

picometer?

Electrons orbit the nucleus of an atom

3. light and/or acid.


#19
M:1 3
<
Electron orbitals around the nucleus of
an atom are generalized by their shape.

because if you were to look for the
electron in that orbital you would
find it somewhere on the sphere. Where
would you probably find an electron
in the second orbital?

H2 is a more stable molecule than H.

together made a more stable substance
than one lone hydrogen atom. Why is
that?

3. hydrogen gets very lonely.


#24
M:2 3
<

study of:
>
1. the sound of molecules.
2. the 3D arrangement of atoms.
3. both of these.


#25
Y:N

atoms can be arranged in the molecule
in two different ways, do you think both
molecules have the exact same
chemical behavior?

Chemists describe reactions using basic
equations. Consider the following
equation showing 4 hydrogen and 2
oxygen making 2 waters: 2H2+O2 -> 2H2O.

a higher orbit around the nucleus of
atom have done what?

#28
M:3 3
<
Of the three elementary particles in an
atom, which one weighs the least?
>
1. proton.
2. neutron.
3. electron.

#29
M:3 3
<
Electrons move around the nucleus of
atoms at very high speeds. This is why
an electron at rest weighs less than
an electron that is moving (actually
there is no such thing as an electron
that is not moving).  If an electron
were, however, to stop moving, how
much would it weigh?
>
1. 0.0001 gram.
2. 0.0000000000000001 gram.
3. 0.0000000000000000000000000001 gram.

M:2 4
<
How much heavier is a proton than an
electron?
>
1. about 200 times heavier.
2. about 2000 times heavier.
3. about 20,000 times heavier.
4. about 2 million times heavier.
