Q.

Whenever we write a chemical equation always we write all the gases in the molecular form . Why don't we do the same with the metals ?

Q. Metallic bodies are held together by metallic bonds, which is the force of attraction between X and Y. Identify X and Y.

1. Valence shell electrons and inner shell electrons
2. Inner shell electrons and the metal ions
3. Metal ions and Metal ions
4. Valence shell electrons and the metal ions

Q. Why does Hydrogen come in reactivity series even when it is not a metal?

Q.

In a metallic substance, the metal ions are held together by a sea of electrons freely roaming between all the ions as shown below. Where do you think this sea of electrons has been accumulated from?

1. All the atoms of the metal
2. Only half of all the atoms of the metal
3. Not the atoms of the metal but from an outside source
4. Only one fourth of all the atoms of the metal

Q. Metals are structures of atoms held together by metallic bonds, which is the force of attraction between X and Y. Identify X and Y.

1. Valence shell electrons and the metal ions
2. Inner shell electrons and the metal ions
3. Valence shell electrons and inner shell electrons
4. Metal electrons and metal ions

Q. When a non-metal reacts with oxygen, it forms a non-metallic oxide. This non-metallic oxide when reacted with $H_{2}O$, form a substance, ‘X’ with pH value less than 7. ‘X’ is:

2. Acidic
3. Basic
4. Neutral

Q. Read the statements and choose the correct option.
i. ‘A’ reacts with oxygen to form an acidic oxide.
ii. ‘B’ reacts with oxygen to form a basic oxide.
iii. Oxides of A and B react with water to form X and Y solutions, respectively.

1. A - Metal, B - Non-metal, X - Acidic, Y - Basic
   
2. A - Non-metal, B - Metal, X - Basic, Y - Acidic
   
3. A - Non-metal, B - Metal, X - Acidic, Y - Basic

Q. Hydrogen gas $\left(H_2\right)$ is used as fuel in rockets and space shuttles. The two hydrogen atoms in $H_2$ gas are bonded to each other by ___.

1. transfer of electrons
2. gaining of electrons
3. forming ions
4. sharing an electron pair

Q.

why hydrogen is included in the metal activity series ?

Q. Assertion :The bond in an $O_2$ molecule is considered to be non-polar.
Reason: The oxygen atoms in an $O_2$ molecule share the bonding electrons equally.
