Pl I’m begging help Determine the Number of Protons, Electrons, and Neutrons For the Following Elements: Vanadium - 53 Copper - 65

Gold - 198 Calcium - 42
Fluorine - 20 Chlorine - 37

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.

answer; 4 electrons;
