An atom is the smallest particle of an element. It is made up of three types of particles such as protons (positively charged), neutrons (uncharged), and electrons (negatively charged). Both protons and neutrons are combined to form a central nucleus and this nucleus is surrounded by electrons. Each element possesses an individual atomic number and atomic weight. The atomic number is determined by the number of protons observed in the nucleus. In the periodic table, the chemical elements are arranged in an order based on the atomic number. The four essential elements in life are hydrogen (H), carbon (C), nitrogen (N), and oxygen (O). These elements are otherwise called bulk elements. Here, hydrogen is a basic element and it owns an atomic number of 1.

Expert Solution & Answer

Answer to Problem 1MCQ

Correct answer:

A neutral hydrogen atom with a mass number of 1 has 0 neutrons, 1 protons, and 1 electrons. Hence, option a. is correct.

Explanation of Solution

Reason for correct answer:

Option a. is given as “0; 1; 1.”

An atomic number of a hydrogen atom is 1, therefore, its proton number will always remain 1. Since the hydrogen atom is neutral, the number of protons in a hydrogen atom is equal to the number of electrons, therefore, its electron number is 1 and 0 neutron. Hence, option a. is correct.

Reasons for incorrect answers:

Option b. is given as “1; 1; 1.”

Here, a neutral hydrogen atom contains 1 neutron, 1 proton, and 1 electron but neutrons are absent in the hydrogen atom. Hence, option b. is incorrect.

Option c. is given as “0; 1; 0.”

Here, a neutral hydrogen atom contains 0 neutron, 1 proton, and 0 electron but in a neutral hydrogen atom, the number of protons is equal to the number of electrons, therefore, the electron number should be in 1. Hence, option c. is incorrect.

Option d. is given as “1; 0; 0.”

Here, a neutral hydrogen atom contains 1 neutron, 0 proton, and 0 electron but an atomic number of a hydrogen atom is 1, therefore, the proton and electron numbers should be in 1 and a net charge of a neutral hydrogen atom is 0. Hence, option d. is incorrect.

Hence, option b., c., and d. are incorrect.

Conclusion

Because of the reasons as mentioned earlier, the condition 0; 1; 1 is considered to be a neutral hydrogen atom with a mass number of 1. Hence, correct option is a.
