(i) IE1 of sodium is lower than that of magnesium While IE2 of sodium is larger than that of magnesium.
This element handles the structural elements of vegetation and animals at cellular, tissue, and organ stages, together with:
Although the number of new attractive and repulsive forces is identical, though the magnitude with the beautiful forces is more. Thus, when two hydrogen atoms approach one another, CBSE Class 11 Biology the overall possible energy from the technique decreases. Hence, a stable molecule of hydrogen is shaped.
Variation along a period of time. On shifting from left to suitable within a interval the nuclear charge boosts along with the atomic dimension decreases as a result ionization enthalpies are anticipated to enhance.
These are remarkably reactive things and therefore occurs in merged condition. On relocating down the group their reactivity increases.
Reply: When two atoms with various electronegativity are connected to each other by covalent bond, the shared electron pair will not from the centre due to the difference in electronegativity. Such as, in hydrogen flouride molecule, flouride has increased electronegativity than hydrogen.
(a) Numerous villi enormously enhance the internal surface area region of the smaller intestine which facilitates the absorption of digested food.
