Write the electronic configuration of any one pair of isotopes and isobars. These valence electrons are responsible for the valency of an atom. An atom consists of a positively charged sphere with electrons embedded in it. Page No 52: If number of electrons in an atom is 8 and number of protons is also 8, then (i) what is the atomic number of the atom and (ii) what is the charge on the atom? Helium atom contains two protons, two electrons and two neutrons making its mass number at 2.

Chapter 4 The Structure Of The Atom Answer Key Questions
N iels Bohr proposed the following postulates regarding the model of the atom. Number of electrons in L-shell, n = 2, 2n2 = 2 × 22 = 8. Thereafter, Bohr's model of an atom is thoroughly explained along with the concept of energy levels. This reactivity is responsible for the formation of molecules between two or more atoms. Using the formula 2n^2 number of electrons in any shell can be calculated. D) The correct electronic configuration of sodium is 2, 8, 1. Schematic atomic structure of the first eighteen elements is shown in the chapter. What is the relation between the two species? Electrons do not radiate energy while revolving. The electrons fill the inner levels first as they follow the stepwise filling of orbitals. J. Chadwick discovered a subatomic particle with no charge and a mass equivalent to protons in the nucleus of all atoms.
Electrons do not radiate energy when revolving in the distinct orbits. Given that these particles make up atoms, they are often referred to as subatomic particles. Different Models on Structure of an Atom. The valency becomes zero for an atom when the outer bounds have eight electrons or no electrons to lose. Also, na me the element. But, an electron revolving in circular orbits will not be stable because during revolution, it will experience acceleration. C) The mass of an electron is about times that of proton. The atoms of the same elements with the same atomic number and different mass numbers. The negatively charged particles present in the outermost shell are called Valence Electrons.

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. Video Solution for structure of the atom (Page: 56, 19). The neutron is the other type of particle found in the nucleus. Page No 55: Question 8: Explain with examples (i) Atomic number, (ii) Mass number, (iii) Isotopes and (iv) Isobars. The maximum number of electrons present in an orbit of n = 1 is given by 2 n 2 = 2 × 1 2 = 2. J. Thomson proposed that the structure of an atom is similar to that of a Christmas pudding where electrons are embedded like currants in the sphere. While revolving, the negatively charged particles do not lose energy in these orbitals or energy levels.
Atoms of a specific element are different from those of any other element. The proton's charge is equal but opposite to the negative charge of the electron. Drawbacks of Thomson's Model: Thomson's structure of an atom failed to explain the arrangement of protons and electrons in its structure. The revolving electron would lose its energy and finally fall into the nucleus, the atom would be highly unstable. The first orbit (i. e., for n = 1) is represented by letter K. Similarly, for n = 2, it is L − shell, for n = 3, it is M − shell and for n = 4, it is N − shell. These rays consist of positively charged particles known as protons. B) A neutron is formed by an electron and a proton combining together. Even the individual protons and neutrons have internal structure, called quarks. It is given that the average atomic mass of the sample of element X is 16.
Chapter 4 The Structure Of The Atom Answer Key Answer
Give any two uses of isotopes. Question 12: If Z = 3, what would be the valency of the element? One of the two types of particles found in the nucleus is the proton. The concept of valency is explained with the help of numerous examples in the chapter, Structure of the Atom. Similarly, for second orbit, it is 2 n 2 = 2×2 2 = 8.
And, the percentage of isotopeis (100 − 10)% = 90%. An atom contains three basic particles namely protons, neutrons and electrons. These orbits or shells are represented by the letter K, L, M, N or the numbers 1, 2, 3, 4. Mass Number is also called Nucleon number. Question 10: If bromine atom is available in the form of, say, two isotopes (49. This nucleus contains most of the atom's mass and is composed of protons and neutrons (except for common hydrogen which has only one proton). The neutron carries no electrical charge and has the same mass as the proton. Most properties of atoms are based on the number and arrangement of their electrons. So, let's get started and cover this topic of CBSE class 9 syllabus. The electrons are located at the outermost regions called the electron shell. Isotopes have the same electronic configuration].
Since the time of the discovery of atoms, there are a variety of theories which were formulated by many renowned scientists. The particle with eight electrons in the outermost shell is an octet, and these molecules are mostly inert in nature. Fundamental Constituents of an Atom. Mass Number = Atomic Number + Number of Neutrons in the Nucleus. Describe the limitations of J. J Thomson's model of the atom. They are protium, deuterium, and tritium. Thus, the valency of oxygen is (8 − 6) i. e., two. The atoms of the nucleus contain distinct orbits of electrons.
