I've tried to fix it up best I could if anyone could have a look at it and give me feedback that'd be great! :D Atoms are comprised of both positive, neutral and negative charges, known as protons, neutrons and electrons. In an atoms nucleus, protons and neutrons are found. For an atom to be...

My textbook states that Heavy elements with atomic numbers > 80 are stable if the neutron : proton ratio is roughly equal to 1.5:1.

So what conditions actually cause a nucleus to become unstable? I was reading this website and it says that the most stable nucletides have a more or less even number of protons and neutrons. My marking criteria states: - Corretly identifies the features...

Hi guys, I'm currently doing an assignment which is based on the nuclear part of "Production of Metals" I'm stuck on a question that's a 3 marker. "Describe the conditions which cause a nucleus to be unstable" I've written this so far: Atoms are comprised of both positive, neutral and negative...

My timetable wasn't that bad surprisingly, it was an exam day after day with just an overlap of PDHPE and IPT. I cannot wait to drop IPT, the subject is such a boring subject when told by my teacher and i don't find it interesting so I'm most likely gonna drop it next year.

Ah I understand thank you!

Hi, I'm having an issue writing out the ionic equation for: Sulphuric Acid + Magnesium H2SO4 + Mg -> MgSO4 + H2 I've rewritten it as: H2 + Mg -> Mg + H2 But the answer section says: 2H + Mg -> Mg + H2 What have I done wrong? Thanks, guys.

I mean, it is for educational use, should be legal.

Noble Gases have complete shell walls and therefore don't require to be joined to other atoms to be complete so they don't react with other elements, In this case, Radon is the one found as a single atom in nature if I'm correct.

I've been given a Gen Maths exam and a Biology exam, PDHPE coming as well. Only assessments I've been given so far is Chemistry.
