Which of the following elements has 3 electrons in the outermost d orbital?

Chemistry
1 answer:
Nina [5.8K]4 years ago
3 0

Answer:

A

Explanation:

Element A has 3 electrons in outermost shell so its valency is 3. It will loose 3 electrons to attain stability, as loss of 3 electrons is easier than gain of 5 electrons.

Valency of B is −2 as it will gain 2 electrons to attain stability and combine with other atom.

Valency of A⟶+3

Valency of B⟶−2

(Refer to Image)

Cross multiply valency of A and B

∴A2B3 compound will be formed.

Explain how dalton’s atomic theory offered a convincing explanation of the observation that mass is conserved in chemical reacti
podryga [215]

Dalton's atomic theory was based on the law of conservation of mass which states that the matter can neither be created nor be destroyed but it can only transformed into one form or another. In a chemical reaction, total mass of the reactants will be equal to the total mass of the products.

Taking an example,

methane+oxygen\rightarrow \text{carbon dioxide}+water

CH_4+2O_2\rightarrow CO_2+2H_2O

Mass of CH_4 = 16g

Mass of 2O_2 = 2\times 32g

Total mass on reactant side = (16+2\times 32)

Total mass on reactant side = 80g

Mass of CO_2 = 44g

Mass of 2H_2O=2\times 18g

Total mass on product side = (44+2\times 18)

Total mass on product side = 80g

It is seen from the above example that the

total mass on reactant side = total mass on product side.
