How does mercury differ from

Question

other metals? (1 point)
It does not conduct
electricity.
It is not solid under
normal conditions.
It does not chemically
react with other
elements.
It is not lustrous.

Answer 1

Mercury differs from other metals primarily because it is not solid under normal conditions. It is a liquid at room temperature, which sets it apart from most other metals that are typically solid. Therefore, the correct answer is:

It is not solid under normal conditions.

Answer 2

Based on patterns in the
periodic table, which
element is the least
malleable in its solid state?
(1 point)
antimony (Sb)
strontium (Sr)
phosphorus (P)
copper (Cu)

Answer 3

Based on patterns in the periodic table, phosphorus (P) is the least malleable in its solid state. While metals such as copper (Cu) and strontium (Sr) are known for their malleability, phosphorus is a nonmetal and is more brittle in its solid form. Therefore, the correct answer is:

phosphorus (P).

Answer 4

Based on patterns in the
periodic table, which
element is the least
malleable in its solid state?
(1 point)
antimony (Sb)
strontium (Sr)
phosphorus (P)
copper (Cu)

Answer 5

Based on patterns in the periodic table, phosphorus (P) is the least malleable in its solid state. While antimony (Sb) is a metalloid, and metals like strontium (Sr) and copper (Cu) are known for their malleability, phosphorus, being a nonmetal, is brittle and therefore not malleable.

So, the correct answer is:

phosphorus (P).

Answer 6

In which group of elements does
tellurium (Te) belong?
(1 point)
metalloids
transition metals
alkali metals
lanthanides

Answer 7

Tellurium (Te) belongs to the group of elements known as metalloids. Metalloids have properties that are intermediate between metals and nonmetals, and tellurium is commonly classified as such.

So, the correct answer is:

metalloids.

Answer 8

Which statement describes
the properties of lanthanoids
and actinoids? (1 point)
They are malleable
and lustrous, and
they tend to be poor
conductors of both
electricity and
thermal energy.
They are brittle and
dull, and they tend to
conduct both
electricity and
thermal energy.
They are malleable
and lustrous, and
they tend to conduct
both electricity and
thermal energy.
They are brittle and
dull, and they tend to
be poor conductors
of both electricity
and thermal energy.

Answer 9

The correct statement describing the properties of lanthanoids and actinoids is:

They are brittle and dull, and they tend to conduct both electricity and thermal energy.

While lanthanoids (the 14 elements following lanthanum) and actinoids (the 14 elements following actinium) do exhibit some metallic properties, they can be brittle and are generally not as malleable as other metals. They can conduct electricity and thermal energy, but their appearance is often dull rather than lustrous.

Answer 10

Which property do the elements in
each column of the representative
elements series of the periodic table
have in common? (1 point)
number of neutrons
number of orbitals
number of protons
number of valence electrons

Answer 11

The property that the elements in each column of the representative elements series of the periodic table have in common is the number of valence electrons. Elements in the same group (column) have the same number of valence electrons, which is responsible for their similar chemical properties.

So, the correct answer is:

number of valence electrons.
