ICSE Class 10 - Properties in Modern Periodic Table Videos
Periodicity in Properties of Elements
The video explains the periodicity trend in a group (similar chemical properties) and in a period (change in the electron affinity).
- Arrange the following as per the instructions given in the brackets (a) Carbon, Fluorine, Beryllium (decreasing order of atomic size) (b) Sulphuric acid, Phosphoric acid, Acetic acid (increasing order of number of replaceable H atoms per molecule) (c) Potassium, Lithium, Sodium (increasing order of ionization potential)
- according to adsorption theory of catalysis, the speed of reaction increase because
- find odd man out:gold ,silver,iron, diamond
- Hi, sir/madam could you please help me to find answer for this question which is the most metallic element and which element having highest atomic radius
- GIVE REASON Electronegativity increases across a period from left to right in the periodic table.Pls let me know-thanks.
- 23 atomic mass, 11 protons, how many neutrons
- Why is lithium regarded in least electronegative
- state the trend in chemical reactivity : I) across the period left to right, 2) down the group
- periodic classification of elements
- which metal has most electron affinity and which has least and why? Na, K, Li, or Cs
