    Guys who said you can't have more than 8 electrons, check the electron distributions on the Internet and he told u what is the number if electrons in the last shell so you can't just assume that it is 3 or 4 the answer is 11 and I'm very very sure

    I will explain it to u, first as you go down the group the number of shells increase this means that the forces of attraction between the nucleus and the valence electrons decrease as there is now more shielding between them. Ty :D P.S if u don't believe check the melting points on the Internet

    dont want u to feel bad but it is wrong actually it is because it provides more ions,ions speed up the reaction, u cant say it acts as a catalyst because the ions are changed by the reaction, and the definition of a catalyst is a substance that speeds up a reaction without being changed by the...

    2 marks one for formula and one for state symbols as some people say but i think it is one mark for balanced and one for formula

    i wrote change in mass/ time taken and yes ratios shud be in whole numbers. but i want to ask u a question did it ask for state symbols in ionic formula? and do i get it wrong if i wrote 2Ag++2Cl-=2AgCl, multipled all by 2 for some reason :/
