LECTURE 3 ( Metals and Non Metal-Alkali and Alkaline) Metals and Non Metals SCIENCE CLASS 10 Edit Delete
Lecture 1 (Basics) 3c) The ionisation energy is the minimum energy required to remove the outermost electron from a gaseous neutral atom to form a cation. Position in a group: X will be above Y ( because of ionisation energy decreases down the group ) Position in a period: X will be the right side of Y ( because ionisation energy increases from left to right) 3d) Two hydrogen atoms combine with one sulphur atom to form hydrogen sulphide (H2S) gas. 4a) Mg, Cl, Na, S, Si (increasing order of atomic size) - Cl < S < Si < Mg < Na 99 pm < 104 pm < 117 pm < 160 pm < 186 pm b. Cs, Na, Li, K, Rb (increasing metallic character) Li < Na < K < Rb < Cs c. Na, K, Cl, S, Si (increasing ionisation potential) - Cl < S < Si < Na < K 1256 < 999 < 786 < 496 < 419 4b) (a) Cl Metals have low ionisation energy and non-metals have high ionisation energy. Also, across the period, ionisation energy tends to increase. The elements P, Na and Cl belong to the third period. Na - Group 1, P - Group 15 and Cl - Group 17. (b) Ne Inert gases have zero electron affinity because of their stable electronic configuration. (c) He Ionisation energy decreases with an increase in the atomic size, i.e. it decreases as one moves down a group. Ne, He and Ar are inert gases. He - Period 1, Ne - Period 2 and Ar - Period 3. 5a) (i) All groups do not contain both metals and non-metals. Group I and II contain only metals. (ii) Atoms of elements in the same group have same number of valence electrons. They have same number of electrons present in their outermost shell. (iii) The non-metallic character increases across a period with increase in atomic number. This is because across the period, the size of atom decreases and the valence shell electrons are held more tightly. (iv) On moving from left to right in a period, the reactivity of elements first decreases and then increases, while in groups, chemical reactivity of metals increases going down the group whereas reactivity of non-metals is decreases down the group.

Lecture 3 (Chemical Properties The density of metals is usually high. Metals are malleable and ductile. Metals form an alloy with other metals or non – metals. Some metals react with air and corrode. For e.g. Iron. Metals are good conductors of heat and electricity. Lead is an exception. Generally, metals are in a solid state at room temperature. Except for Mercury. Mercury is in a liquid state. Many metals produce metal oxide by burning in the oxygen of the air. Highly reactive metals react violently when they’re burnt in oxygen. Metals like sodium and potassium are stored in oil as they react with air in seconds. They’re highly reactive metals. Less reactive metals like gold, silver, platinum, etc do not tarnish easily. They stay shiny and lustrous. Metals produce metal oxide and hydrogen gas while reacting with water. Soluble metal oxides dissolve in water and create metal hydroxide. Not all metals react with water. However, highly reactive metals like sodium and potassium react with water violently and an exothermic reaction takes places where the hydrogen immediately catches fire. Salt and hydrogen are produced when a metal reacts with an acid. Generally, a metal displaces a less reactive metal in a metal salt solution. SCIENCE CLASS 10 Edit Delete
