The weight of an atom is determined by the number of neutrons and protons that are present in the nucleus. The proton and neutron, which are similar in mass, each weighs approximately 1836 times greater than a single electron, thus the mass contributed by electrons is insignificant when determining atomic weight or atomic mass. The atomic mass is the sum of the protons and neutrons in the nucleus. Carbon has an atomic mass of twelve. Since there are six protons and six neutrons in the nucleus(i)How can you calculate atomic mass of an atom? (ii)What is the atomic number of carbon?(iii)In 16O8, the number 16 stands for----------- (a)Atomic number (b) Atomic mass (c) Atomic mass scale (d) Number of electron(iv)How many neutrons oxygen has? |
|
Answer» (i) Atomic MASS = no. of NEUTRONS + no. of protons (ii) 6 (iii) b (atomic mass) (iv) 8 |

Give your own examples that illustrate how metal is lustrous, ductile, malleable, conductive, and can be mixed with other materials to make an alloy. |
|
Answer» Answer: Lustrous => It is the PROPERTY of many metals (exception, Diamond, a non metal) which MAKES them shine by reflecting the light falling on their surface, when it is polished, e.g., iron rods, gold, silver. Malleability => It is the property of any SOLID and hard metal (and/or non metal) which makes them DEFORMED under pressure. It helps to make thin sheets of metals, e.g., tin cans, foils, etc. The materials are called “malleable materials”. Ductility => It is the ability of solid and hard metals (and/or non metals) which can be stretched under tensile strength, e.g., thin wires, etc. |

Case-based questionIn the year 1817, a German chemist, arranged certain elements with similar properties (both physical and chemical) in groups of three. The basis of the arrangement was the atomic masses of the elements. In a particular group, the elements (e.g., A,B,C) with atomic masses 7,23 and 39 respectively were arranged in order of increasing atomic masses and the atomic mass of the middle element (B)was almost the mean or the average of the atomic masses of the first and third elements i.e.; A and C.(i) Which of the following scientist had proposed such a classification of elements?(a) Henry Mosely (b) Dimitri Mendeleev(c) John Newlands (d) Johann Dobereiner(ii) What could be the elements A,B and C?(a) Calcium, Strontium and Barium (b) Lithium, Sodium and Potassium(c)Lithium, Sodium and Calcium (d) Nitrogen, Calcium and Iodine (iii) The three imaginary elements X,Y & Z represent elements according to the given law. If the atomic mass of element X is 14 and that of Y is 46, then the atomic mass of element Z will be:(a) 78 (b) 32 (c) 18 (d) 60(iv) What is the limitation of law discussed in the given paragraph?(a) This law could not explain the position of isotopes(b) This law proved to be true for elements only up to calcium(c) This law could define a total of 9 elements only(d) This law could not define the position of Hydrogen |
