Determine the best formula for reacting elements.
2 answers:
Answer: Option (B) is the correct answer.
Explanation:
Calcium is a metal and iodine is a non-metal. So, when calcium and iodine combine with each other then calcium will donate its excess of electrons to the iodine atom. Thus, it will form an ionic bond.
When calcium reacts with iodine then it results in the formation of calcium iodide.
The reaction equation will be as follows.

Answer:
Explanation:
Chlorine has electronic configuration of 2 , 8 , 7
In n = 3 there are 7 electrons out of which 2 are in s , and 5 are in p . But out of 5 electrons in p , one electron jumps into d orbital . so the electronic configuration becomes as follows
= 7
These orbitals like sp³d hybridise to form 7 degenerate orbitals out of which 2 orbitals contain electrons in pairs and rest three are singly occupied by electrons.( unpaired electrons )
