Select the Correct Statement from the Following

Introduction

In this article, we will be discussing the fundamental particles that make up atoms, the mass of electrons, the isotopes of hydrogen, and the collective term for protons and neutrons. We will analyze each statement and determine which one is correct.

Statement a) Atoms are made up of two fundamental particles.

Atoms are the building blocks of matter, and they are composed of three fundamental particles: protons, neutrons, and electrons. Protons and neutrons are found in the nucleus of an atom, while electrons orbit around the nucleus. Therefore, statement a) is incorrect.

Statement b) Mass of e- is 9.1×10-³1kg.

The mass of an electron is a fundamental constant in physics, and it is approximately 9.11×10^-31 kilograms. This value is a well-established fact in physics and is used in various calculations. Therefore, statement b) is correct.

Statement c) Hydrogen has three isotopes _1¹H,1 ²H,1 ³H.

Hydrogen is the lightest and most abundant element in the universe, and it has three naturally occurring isotopes: protium (¹H), deuterium (²H), and tritium (³H). However, tritium is a rare isotope that is not found naturally and is produced artificially. Therefore, statement c) is partially correct, but it should be noted that tritium is not a naturally occurring isotope.

Statement d) Protons and neutrons are collectively called nucleons.

Protons and neutrons are indeed collectively called nucleons, and they are found in the nucleus of an atom. Nucleons are the building blocks of the nucleus, and they play a crucial role in determining the properties of an atom. Therefore, statement d) is correct.

Conclusion

In conclusion, the correct statements from the given options are:

  • b) Mass of e- is 9.1×10-³1kg.
  • d) Protons and neutrons are collectively called nucleons.

The other statements are either partially correct or incorrect. It is essential to understand the fundamental particles that make up atoms and the properties of these particles to appreciate the complexity of atomic structure.

    Q&A: Understanding Atoms and Their Components

Introduction

In our previous article, we discussed the fundamental particles that make up atoms and the properties of these particles. In this article, we will answer some frequently asked questions related to atoms and their components.

Q1: What are the fundamental particles that make up atoms?

A1: Atoms are composed of three fundamental particles: protons, neutrons, and electrons. Protons and neutrons are found in the nucleus of an atom, while electrons orbit around the nucleus.

Q2: What is the mass of an electron?

A2: The mass of an electron is approximately 9.11×10^-31 kilograms. This value is a well-established fact in physics and is used in various calculations.

Q3: How many naturally occurring isotopes of hydrogen are there?

A3: Hydrogen has three naturally occurring isotopes: protium (¹H), deuterium (²H), and tritium (³H). However, tritium is a rare isotope that is not found naturally and is produced artificially.

Q4: What is the collective term for protons and neutrons?

A4: Protons and neutrons are collectively called nucleons. Nucleons are the building blocks of the nucleus, and they play a crucial role in determining the properties of an atom.

Q5: What is the difference between protons and neutrons?

A5: Protons and neutrons are both found in the nucleus of an atom, but they have different properties. Protons have a positive charge, while neutrons have no charge. The number of protons in an atom determines the element of an atom, while the number of neutrons determines the isotope of an element.

Q6: What is the role of electrons in an atom?

A6: Electrons orbit around the nucleus of an atom and play a crucial role in determining the chemical properties of an element. The number of electrons in an atom determines the chemical properties of an element, such as its reactivity and ability to form bonds with other elements.

Q7: What is the atomic number of an element?

A7: The atomic number of an element is the number of protons in the nucleus of an atom. This number determines the element of an atom and is used to identify elements on the periodic table.

Q8: What is the mass number of an element?

A8: The mass number of an element is the total number of protons and neutrons in the nucleus of an atom. This number determines the isotope of an element and is used to identify isotopes on the periodic table.

Q9: What is the difference between an atom and a molecule?

A9: An atom is the smallest unit of a chemical element, while a molecule is a group of atoms that are chemically bonded together. Molecules can be composed of atoms of the same element or different elements.

Q10: What is the importance of understanding atoms and their components?

A10: Understanding atoms and their components is crucial in various fields, such as chemistry, physics, and materials science. It helps us to understand the properties of elements and compounds, and how they interact with each other.

Conclusion

In conclusion, understanding atoms and their components is essential in various fields. By answering these frequently asked questions, we hope to provide a better understanding of the fundamental particles that make up atoms and their properties.
