Which of the following is false?

An element is defined by its atomic number.
Ninety-two elements occur naturally.
An atom consists of subatomic particles.
Electron shells increase in energy closer to the nucleus.

Expert Solution & Answer

Summary Introduction

Introduction:

An element is considered as the smallest unit of matter, which cannot be broken down into simpler substances, and it is composed of atoms. An atom is the fundamental building block of a chemical element. The atom contains subatomic particles: electron, proton, and neutron.

Answer to Problem 1MC

Correct answer:

Electron shells increase in energy closer to the nucleus is the false statement.

Explanation of Solution

Explanation for the correct answer:

Option (d) is given that the electron shells increase in energy closer to the nucleus is the false statement. An atom's electron shell can accommodate 2n² electrons, where n is the energy level. The electrons/shells closer to the nucleus have the minimum energy, while the electrons with higher energy are far from the nucleus, and so, they are able to jump from one level to another level upon slight excitation. Hence, option (d) is correct.

Explanation for incorrect answers:

Option (a) is given that the element is defined by an atomic number is a false statement. An element can be defined as the substance that cannot be broken down into a simpler substance. Element is defined by its atomic number, which denotes the number of protons found within the nucleus, which makes element unique. The statement is true and not false. So, it is an incorrect answer.

Option (b) is given that the 92 elements occur naturally is a false statement. However, there are 92 naturally occurring elements found on the earth. Every element has a unique atomic symbol. The statement is true and not false. So, it is an incorrect answer.

Option (c) is given that an atom consists of subatomic particles is a false statement. An atom is composed of subatomic particles, including neutrons, electrons, and protons. Protons and neutrons are found inside its nucleus, while electrons are found in its orbits. The statement is true and not false. So, it is an incorrect answer.

Hence, options (a), (b), and (c) are incorrect.

Conclusion

Hence, in an atom, the energy of orbit increases with increase in distance from the nucleus rather than being closer to the nucleus. This difference in energy allows the electrons to jump from one level to the next level when energy is supplied.
