Part B: Write the electron configuration for the following elements. 1. Indium (In)
2. Lead (P5)
3. Osmium (Os)

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

i dont know the answe

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
