Your friend tells you about an article that he read in a tabloid that reported the discovery of a new form of carbon containing eight protons in the nucleus of its atoms. He claims that scientists are eager to explore the properties of this new form of carbon. What is wrong with the tabloid's claim? a. Nothing. The claim is believable. b. The claim must be false because an atom with eight protons would be oxygen, which is already known. c. The claim must be false because all forms of carbon are already known.

Your friend tells you about an article that he read in a tabloid that reported the discovery of a new form of carbon containing eight protons in the nucleus of its atoms. He claims that scientists are eager to explore the properties of this new form of carbon. What is wrong with the tabloid's claim?

a. Nothing. The claim is believable.

b. The claim must be false because an atom with eight protons would be oxygen, which is already known.

c. The claim must be false because all forms of carbon are already known.

Interpretation Introduction

Interpretation:

The correctness of the tabloid’s claim is to be judged.

Concept introduction:

An atom of an element can be identified by the number of protons it contains. This is termed as the atomic number and is a characteristic of an element. It is also equal to the number of electrons present in an atom of that element. It remains the same for all isotopes of that element.

Explanation of Solution

Reason for the correct option:

Option (b) is correct because the tabloid claims that the atom contains eights protons, which means that the atomic number of the element is eight. It is a known fact that the atomic number of oxygen is eight. Also, the atomic number is unique for every element. Therefore, the claim must be false.

Hence, option (b) is correct.

Reasons for the incorrect options:

Option (a) is incorrect because it is known that the atomic number of carbon is six and that of the newly discovered atom is eight...
