Summary Introduction

Introduction: Proton is a positively charged subatomic particle that is present in the nucleus of an atom. The number of protons present in that atom is equal to the atomic number of any atom

Answer to Problem 1SQ

Correct answer: Hydrogen atom has only one proton. Option a. is given as “hydrogen”. Hence, Option a. is the correct answer.

Explanation of Solution

Reasons for the correct statements:

Hydrogen is a lightest element in the periodic table with the standard atomic weight of 1.008.

Option a. is given as “Hydrogen”. The atomic number of hydrogen ion is one. As the number of protons present in the nucleus is called atomic number, the hydrogen atom has only one proton. Hence, option a. is the correct answer.

Reasons for the incorrect statements:

Option b. is given as “an isotope”. An isotope of two or more atoms of the same element has the same number of protons but different number of neutrons. However, only the isotopes of the hydrogen atom contain one proton. Hence, option b. is an incorrect answer.

Option c. is given as “a free radical”. Free radical is an atom with an unpaired electron in its outer ring. Hence, option c. is an incorrect answer.

Option d. is given as “a radioisotope”. The atoms that have an unstable combination of neutrons and protons are called as radioisotopes. They contain more than one proton. Hence, option d. is an incorrect answer.

Hence, options b., c., and d. are incorrect answers.

Conclusion

The hydrogen atom has only one proton.

All organisms need nitrogen in order to grow and repair. Although nitrogen exists in its elemental form in the atmosphere, it cannot be directly used by plants. 7 Where else can plants obtain their nitrogen from? Plants make their own nitrogen.
