$\huge \bf \bigstar_!! \red{ANSWER}!_! \bigstar$

• Elements which exist in solid state are iron,aluminium.
• Elements which exist in liquid state are bromine,Iodine.
• Elements which exist in gaseous state are Oxygen,Hydrogen.

Answer 2

Answer:

Two elements which exist in Solid state = Copper, Gold

Two elements which exist in Liquid state = Bromine, Mercury

Two elements which exist in Gaseous state = Fluorine, Helium  

QUICK FACTS :-

Copper

• Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29.
• It is a member of group 11 and period 4 in the periodic table.
• Copper is one of the least reactive metals, i.e., It will react, but slowly.

Gold

• Gold is a chemical element with the symbol Au (from Latin: aurum) and atomic number 79.
• A dense lustrous yellow precious metal of Group 11, Period 6, of the periodic table.
• Gold is a soft metal that is largely unreactive( a noble metal). That's the reason why jewelry made of gold can be used for a long time.

Bromine

• Bromine is a chemical element with the symbol Br and atomic number 35.
• It is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly colored gas.
• It is a member of group 17 and period 4 in the periodic table.

Mercury

• Mercury is a chemical element with the symbol Hg (from latin: hydrargyrum) and atomic number 80.
• It belongs to group 12 and period 6 in the periodic table.
• Only metal which is liquid at room temperature.

Fluorine

• Fluorine is a chemical element with the symbol F and atomic number 9.
• At room temperature, fluorine is a gas of diatomic molecules, pale yellow when pure

• It is a member of group 17 and period 2 of the periodic table.

Helium

• Helium is a chemical element with the symbol He and atomic number 2.
• It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table
• Belongs to Group 18 and period 1 of the periodic table.
