1
A positive ion is
an atom that lost an electron
one that has an equal amount of electrons to neutrons
one that has an equal amount of protons to neutrons
an atom that gains an electron
2
Neutrons are found
in the inner most energy level around the nucleus
in the outermost energy level around the nucleus.
in the nucleus.
after you subtract the atomic number from the # of electrons
3
When two negative charges are near each other
they will coexist
they will be attracted to each other
they will repel each other
they will need counseling to correct their attitudes
4
The atomic number tells you
how many protons there are in an element.
how many neutrons there are in an element
how many protons or electrons in a neutral atom.
the amount of mass the atom is.
5
Protons are found
in the outer most energy level of the atom
on the periodic table
in the nucleus
in the lowest energy level outside of the nucleus
6
A column on a periodic table is called
a group or a flock
a group
a period
a group or a family
7
The elements are arranged on the periodic table by
when they were discovered
their atomic mass
by their atomic number
by how often they are used
8
A chemical symbol is
always one capital letter
there are no rules on how to write a chemical symbol
always a lower case letter
a capital letter and lower case letter(s) after it
9
What is the negative charge in an atom called?
quark
proton
neutron
electron
10
What is the positive charge in an atom called?
neutron
proton
quark
electron
11
Electrons are found
in the outer energy level of an atom only
in energy levels surrounding the nuclues
only in the inner energy level
in the nucleus of an atom
12
When a positive charge and another positive charge are near each other
they repel each other
will not have a reaction
will earn a good grade on project after working together
they are attracted to each other
13
We round the atomic mass to the nearest
nearest hundredth
ten
whole number
tenth
14
A row on the periodic table is called
energy level
family
period
group
15
Ther person responsible for arranging the periodic table is
Gregor Mendel
C. Columbus
Dmitri Mendeleev
W. Mozart
16
There is a particle in the atom that has no charge. What is it?
electron
proton
quark
neutron
17
In covalent bonding electrons are
lost or gained by an atom
gained by an atom
lost by an atom
shared with another atom
18
To find the number of neutrons there are in an atom you
need to look at the atomic number
you take the atomic mass- the atomic number.
you need to subtract the number of electrons from the atom.
need to look at the the atomic mass
19
A negative ion
is an atom that gained an electron
has an equal number of protons to electrons
has an equal number of electrons to neutrons
is an atom that lost an electron
20
The number of protons is special because
it tells you the volume of the atom
it tells you how many electrons there are in the atom.
it tells you how many neutrons there are in the atom.
each element has its own number of protons.
