Diagram shows the electron configuration of an atom, of an element, for the electrons in the s and p orbitals Which group number represents the element shown?
A) 1
B) 2
C) 13
D) 15

outer ring has 5 electrons
inner ring has 2 electrons

there are only 2 rings exterior of the nucleus

BAN ME

MUAHAHAHAdHHA

i see you when you sleep

Step-by-step explanation:

Explanation:

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.
