Chapter 2, Problem 1MCQ
Summary Introduction

Introduction :

The smallest unit of matter that forms a component of a composite is called a particle. Every solid, liquid, gas, and form of plasma is composed of unrestricted or ionized iotas. The average size of a particle is 100 picometers. The protons, which are strongly charged, and the neutrons are found at the particle's center (focus) (no charge). The electrons are located in the molecule's outer regions, which are referred to as its "electron shells" (contrarily charged).

Answer to Problem 1MCQ

Correct answer :

The correct answer is option (c) 0;0;1.

Explanation of Solution

Explanation/justification for the correct answer :

Option (c) 0;0;1. 1 H+ alludes typically to a decidedly charged particle of a hydrogen molecule, consequently an iota from which one electron is taken out. Since H particles comprise one proton and one electron, if one eliminates the electron, one is left with a proton. In this way, 1 H+, as a rule, alludes to only one proton left when the hydrogen iota's electron was taken out or uprooted. So, the correct answer is option (c).

Explanation for incorrect answer :

Option (a) 1;0;2. The simplest particles, consisting of just one proton and one electron, are found in the component hydrogen. The core is shaped by the proton, and the electron revolves around it. Any remaining elements, such as helium, contain neutrons in their cores exactly as protons do. In general, the strongly charged protons will repel one another, while the neutrons support the stability of the core. Nuclear mass is determined by the number of protons in the nuclear number and the number of protons in addition to neutrons. Since there is just one proton and no neutrons, hydrogen has a nuclear mass of 1. Thus, it is an incorrect option.

Option (b) 0;1;0. Nuclear mass is determined by the number of protons in the nuclear number and the number of protons in addition to neutrons. Since there is just one proton and no neutrons, hydrogen has a nuclear mass of 1. So, this is an incorrect answer.

Option (d) 1;1;0. Nuclear mass is determined by the number of protons in the nuclear number and the number of protons in addition to neutrons. Since there is just one proton and no neutrons, hydrogen has a nuclear mass of 1.
