Question
With regard to the species 16O2-, 19F- and 20Ne, which of the following statements is correct?*1 point(a) All three species contain 10 electrons.(b)The sum of the neutrons in all three species is 27.(c) The sum of the protons in all three species is 28.(d) Both 19F- and 20Ne contain 20 neutrons.(e) none of the above
Solution
Let's break down each option:
(a) All three species contain 10 electrons.
- 16O2-: Oxygen normally has 8 electrons, but the 2- charge indicates it has gained 2 additional electrons, so it has 10 electrons.
- 19F-: Fluorine normally has 9 electrons, but the 1- charge indicates it has gained 1 additional electron, so it has 10 electrons.
- 20Ne: Neon is a noble gas and has 10 electrons. So, statement
