Chapter 2, Problem 1SQ

What atom has only one proton?

a. hydrogen
b. an isotope
c. a free radical
d. a radioisotope

Expert Solution & Answer

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.

Q8. A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out. What type of bias is there in this study? If the company who makes the medication funds this research, what type of bias might exist in this research work?
