All atoms of a given element are identical, having the same size, mass and chemical properties. Question 13: Composition of the nuclei of two atomic species X and Y are given as under. Therefore, 2 electrons go to K-shell and 8 electrons go to L-shell, thereby completely filling K and L shells. The maximum number of electrons that can occupy K and L-shells of an atom are 2 and 8 respectively. Neutrons are neutral. Science NCERT Grade 9, Chapter 4, Structure of the Atom is a continuation of the previous chapter with a focus on different subatomic particles and the various models that have been proposed to explain how these particles are arranged within the atom. If K and L shells of an atom are full, then what would be the total number of electrons in the atom? Rutherford conducted an experiment bombarding the alpha (α)-particles on a gold foil. The different energy levels are shown in the diagram. Chapter 4 the structure of the atom answer key 2022. Question 3: Draw a sketch of Bohr's model of an atom with three shells. These subatomic particles cannot be freed and studied in isolation.

Chapter 4 The Structure Of The Atom Answer Key Pdf

Bohr's model gives an elaborative explanation on the structure of an atom and overcomes the objections faced by all the other models on the structure of an atom. Similarly, Helium (He) has 2 electrons in its outer shell, Neon (Ne) (2, 8, and 8) has eight electrons in its outer shell. Its electronic configuration is 2, 1. Chapter 4-The Structure of the Atom Flashcards. For Example, in Calcium, atomic number 20, and argon, atomic number 18, the mass number of both these elements is 40. An atom is electrically neutral as the protons and electrons are equal in magnitude. Number of electrons. The number of protons in the nucleus of an atom determines what kind of chemical element it is.

Chapter 4 The Structure Of The Atom Answer Key Grade 6

The nucleus of an atom consists of Protons, and the atomic number is equal to the number of protons present in one atom of an element. Therefore, an atom containing one electron and one proton will not carry any charge. The mass of a proton is approximately 2000 times as the mass of an electron. Atoms cannot be created, divided into smaller particles, or destroyed. For third orbit, it is 2 n 2 = 2 × 3 2 = 18. I) Only certain orbits known as discrete orbits of electrons are allowed inside the atom. B) different chemical properties. Chapter 4 the structure of the atom answer key pdf. What are the percentages of isotopes and in the sample? Terms in this set (40). Page No 47: Question 1: What are canal rays? Question 15: Put tick () against correct choice and cross () against wrong choice in the following question: Rutherford's alpha-particle scattering experiment was responsible for the discovery of.

The neutron carries no electrical charge and has the same mass as the proton. Chapter 4 the structure of the atom answer key book. These discrete orbits or shells are shown in the following diagram. Question 7: Define valency by taking examples of silicon and oxygen. The distribution of electrons in different orbits are explained in detail along with the rules which must be followed while writing the number of electrons in different energy levels. An atom contains three basic particles namely protons, neutrons and electrons.

Isotopes and Isobars are important concepts that you must understand for getting a better grip over the chapter. Hence, the valency of the element is 1 (since the outermost shell has only one electron). Subsequently, Rutherford's model of an atom is explained and his scattering experiment of alpha particles by a gold foil is discussed extensively. Other sets by this creator. Question 11: The average atomic mass of a sample of an element X is 16. The particles deflected 180 0 after bombarding the nucleus. Page No 53: For the symbol H, D and T tabulate three sub-atomic particles found in each of them. Recommended textbook solutions. Electrons do not radiate energy while revolving. The hydrogen atom (H) contains only one proton, one electron, and no neutrons.
