Question

Match all the terms that apply to each element. Some terms may apply to more than one element.

a. Main group element
b. halogen
c. noble gas
d. inner transition element
e. alkaline earth
f. Non-metal
g. Alkali metal
h. Metalloid
i. Metal

1. Titanium
2. Gold
3. Argon
4. Thallium

Answer 1

Answer:

Titanium - Metal

Gold - Metal

Argon - noble gas

Thallium - Metal

Explanation:

A metal is a species that easily looses electrons to yield a positive ion. Metals are found in the left hand side of the periodic table.

Thallium is a groups 13 metal, gold is a group 11 metal while titanium is a 4 metal.

However, argon is a noble gas hence it belongs to groups 18 of the periodic table.

Answer 2

Titanium -metal

gold - metal,

Argon - noble gas

Thallium -metal, transition metal

Explanation:

In modern periodic table :

• Metals are listed from the middle to left-hand side of the periodic table
• Nonmetals are listed on the upper right-hand side of the periodic table
• Metalloids divide the periodic table in a zig-zag line with nonmetals on the right and metals on the left.
• The alkali metals are listed under group 1
• The alkaline earth metals are listed under group 2
• The noble gases are listed under group 18
• The transition metals are listed from group 3 to group 12.
• The halogens are listed under group 17
• The inner transition elements (f-block) are listed at the bottom separately.

So, from this, we can match the given elements as:

Titanium -metal

gold - metal,

Argon - noble gas

Thallium -metal. transition metal
