Total questions: 35
Worksheet time: 18mins
The order of the elements in the periodic table is based on

the number of neutrons in the nucleus.
atomic mass.
Semiconductors are elements that
have large atomic masses but small atomic numbers.
do not form compounds.
can conduct heat and electricity under certain conditions.
are extremely hard.
In Mendeleev's periodic table, elements in each column had similar
atomic masses.
propeties
atomic number.
symbols.
Magnesium (Mg) is located to the right of sodium (Na) because Mg has
fewer protons.
no neutrons.
no protons.

What is Mendeleev is known for?
creating today's atomic model
discovering protons
publishing the first periodic table

Mendeleev left gaps in his periodic table because
the table was too small.
protons belonged there.
the table was too full.
no known elements fit there.
Each column of the periodic table is

The periodic law states that elements that have similar properties appear
to the left of each other.
to the right of each other.
at every tenth element.
at regular intervals.
As you move from up to down in a column of the periodic table, elements have
fewer protons.
a lower atomic number.
a higher atomic number.

protons.
neutrons.
ions.
valence electrons.
Which statement about noble gases is correct?
They form compounds with very bright colors.
They exist as single atoms rather than as molecules.
They are highly reactive with both metals and nonmetals.
They are extremely rare in nature.
As one moves from left to right across a period in the modern periodic table, elements become
smaller.
lighter.
less metallic.
more unlike each other.
Elements that are found in the same group have the same number of
protons.
neutrons.
valence electrons.
protons and neutrons.
