Pls explain the question fast
Solution
The structure of atom is as follows:
The whole mass is concentrated inside the nucleus because protons and neutrons that account for mass of an atom are present in the nucleus. The mass of electrons is negligible.
An atom is divisble into subatomic particles called electrons, protons and neutrons. It is not indivisible.
An atom is electrically neutral because number of electrons (negatively charged) and protons (positively charged) are equal in an atom while neutrons do not carry any charge.
All the atoms are not stable in their basic state because every atom needs to have inert gas configuration, i.e., duplet or octet of valence electrons to be stable. Those atoms which do not have such inert gas configurations in their basic state are not stable.
Therefore, statements (ii) and (iv) are incorrect.
Hence, the correct answer is option (c).
