Question

which of the following subatomic particle is not present in an atom of hydrogen (a)electron ,(b)proton ,(c)neutron ,(d)both (b) and (c)​

Answer 1

Answer:

(c) Neutron

Explanation:

Neutron is the subatomic particle which isn't present in an atom of hydrogen.

Hydrogen has 1 proton and 1 electron.

Some More Information :

• Hydrogen is the smallest atom.
• Its valency is 1.
• An atom is the smallest particle of an element that can participate in a chemical reaction.
• Atoms were thought to be indivisible but they can be divided under some circumstances.
• There are three sub-atomic particles in an atom :-

1. Electron
2. Proton
3. Neutron

• An electron is a sub-atomic particle of atom that carries a negative charge.
• A proton is a sub-atomic particle of atom that carries a positive charge.
• A neutron is a sub-atomic particle of atom that carries no charge.

Answer 2

$\bf \bigstar \: \underline{Correct \: Question} :$

Which of the following subatomic particle is not present in an atom of hydrogen

• (a)electron
• (b)proton
• (c)neutron
• (d)both
• (b) and (c)

$\bf \bigstar \: \underline{Correct \: Solution} :$

$\rm\implies\: \underline{Option \: c) \:neutron \: is \: correct} :$

$\bf \bigstar \: \underline{Explanation:}$

• The three main subatomic particles found in an atom are Protons, neutrons, and electrons but in case of hydrogen neutron or neutral subatomic particle which is very important constituent of every atomic nucleus is not present in ordinary hydrogen atom and Hydrogen atoms consists only proton, electrons.

• Hydrogen atom nucleus is smallest in size due to this it cannot accommodate any heavier neutron. Henceforth it also makes hydrogen atom unstable in nature .Due to this hydrogen atom does not contain neutron .

$\bf \bigstar \: \underline{Additional \: \: Information} :$

• Atoms are tiny particles which contain three sub-atomic particles namely know as protons, neutrons and electrons

• Electrons are negatively charged subatomic molecules

• Protons are positively charged subatomic particles

• Neutrons are neutral charged subatomic particles.
