FAQs on Structure of atom PPT Chemistry Class 11

1. What is the structure of an atom?
Ans. The structure of an atom consists of a nucleus containing protons and neutrons, surrounded by electrons in energy levels or shells.
2. How are protons, neutrons, and electrons arranged in an atom?
Ans. Protons and neutrons are located in the nucleus at the center of the atom, while electrons orbit the nucleus in specific energy levels or electron shells.
3. What are the charges of protons, neutrons, and electrons?
Ans. Protons have a positive charge, electrons have a negative charge, and neutrons have no charge (they are neutral).
4. How do electrons determine the chemical properties of an atom?
Ans. The number and arrangement of electrons in an atom's energy levels determine its chemical properties. The outermost energy level, known as the valence shell, is particularly important in determining the reactivity and bonding behavior of an atom.
5. Can atoms of different elements have the same number of protons?
Ans. No, atoms of different elements cannot have the same number of protons. The number of protons in the nucleus determines the element's identity.
