Spelling is shocking and answers aren't all correct, atom is the smallest thing in the universe?  False is incorrect? What are atoms made of? Neutrons, protons and electrons.  they are even made up of further things called quarks and neutrinos

Helpful quiz,
although there are some spelling mistakes,

and atoms are made of even smaller things...

Plus alkanes are saturated and alkenes are unsaturated

but anyway thanks for the quiz :)

sorry about spellings English was never mt best subject and i had some trouble with the quiz it wouldn't let me select the correct answers for some reasons and i never knew about quarks and neutrinos im only at gcse  unit 1 atm

Good, however an Unsaturated HydroCarbon is called and AlkEne not AlkAne.

bilal

Report

unsaturated hydrocarbon is alkene not alkane.

Unsaturated is alkene not alkane .

also atoms are not the smallest thing in the universe, even at GCSE level you should know that.
