This blog will cover and explain the specification for Edexcel triple science course 2013 Chemistry. Hope it helps :)
What does relative charge actually mean?
Protons and electrons both have electrical charges.They both have the same strength of electrical charge, just one negative and one positive. If we say the strength is '1' the we are making the charge relative (in proportion) to the protons and electrons.
I think electron relative mass 1/1859 approx....
that is right!!!
Electrons have a relative mass of 1/1836 however 1/2000 is accepted
Hi Sam! So will you definitely get a mark if you put 1/2000?
