Metals- Types And Properties

2.

Select the options which mostly describe transition metals.

Poor corrosion resistance
Hard and strong
High density
Low boiling points

Correct Answer(s)

A. Hard and strong
A. High density

Explanation

The first answer is incorrect. Most transition metals are known for their resistance to corrosion. This trait makes them more useful in a variety of situations.
The second answer is correct. Transition metals are generally hard and strong.
The third answer is correct. Transition metals are generally quite dense.
The fourth answer is incorrect. Transition metals often have quite high melting and boiling points.
It is some of these general properties of transition metals that make them among the most useful metallic elements.

This is the name for the elements in group 1.

Akali Earth Metals
Transition Metals
Alkali Metals
Halogens

Correct Answer

A. Alkali Metals

Explanation

The answer to this question is Alkali Metals. Alkali Metals are in group one because they only have one electron in their valance shell.

A positively charged ion is called a ___________.

Correct Answer
Cation
cation

Explanation
A cation is a positively charged ion, or an ion that has more protons than electrons.

Alkali metals can usually be

Tested for using the flame test
Found in their pure states
Cut with a knife
Non reactive

Correct Answer(s)

A. Tested for using the flame test
A. Cut with a knife

Explanation

The first answer is correct. When adding an alkali metal to water, they will fizz, catch fire, and possibly even explode. This is because they are highly reactive as a result of their single valance electron.

The second answer is incorrect. Due to the high reactivity of these metals, they are rarely found in their native state, as they have usually reacted with something in their environment.

The third answer is correct. Many alkali metals are soft, and can be cut with a knife.

The fourth answer is incorrect. Due to the single electron in the valance shell, these metals are extremely reactive and somewhat dangerous as a result.

The columns in the periodic table are called groups.

True
False

Correct Answer

A. True

Explanation

This is a true statement. The columns in the periodic table are called groups. The rows are called periods.

Select the traits of aluminum.

Reacts strongly with iodine
High density
High melting point
Most common metal in Earth's crust

Correct Answer(s)

A. Reacts strongly with iodine
A. High melting point
A. Most common metal in Earth's crust

Explanation

Aluminum has many unique characteristics distinguishing it from other metals. This question displays them clearly.

Which of the following is not true about the periodic table?

The periodic table arranges all the elements in groups according to their properties.
The periodic table catalogs reactions among elements.
Hydrogen is often separated because it is not technically an alkali metal
All of the elements in the same group have similar PROPERTIES

Correct Answer

A. The periodic table catalogs reactions among elements.

Explanation

The second answer is incorrect. The periodic table organizes elements, which gives some idea of how they might react, but does not categorize their actual reaction.
