Question

trends for the following


1. Effective NucleurCharge
2. Atomic Radius
3. Ionisation Energy
4. Electron Gain Enthalpy
5. Electronegativity


best answer will be marked as BRAINLIEST ​

Answer 1

• 1. Effective NucleurCharge: the nuclear charge on the inside atom decrease on going left--->right in a group as the size of the atom increases.
• Atomic Radius: on going left --->right in a group atomic radius decrases as the number of atom increases.
• Ionisation Energy: on going left--->right in a period I.E. first increases then decrease due to anonymous nature of elements.
• Electron Gain Enthalpy: on going left--->right in a group Electron Gain Enthalpy of an atom.
• Electronegativity: on going left--->right in a group Electronegativity increases.

Answer 2

Explanation:

(1.) increase from left to right and decrease from upper to lower

(2.)increase from upper to lower and decrease from left to right

(3.) increase from left to right and decrease from upper to lower

(4.)increase from left to right and decrease from upper to lower

(5.)increase from left to right and decrease from upper to lower...
