Edexcel Additional Sciences: Chemistry C2 - Structure of an atom
Flashcards do conjunto (8)
- 1_____ are the smallest particles of an element that can take part in chemical reactions.Atoms.
- 2Atoms are made of three types of subatomic particle.Protons and Neutrons (In the nucleus) and electrons (In the shells/ energy levels)
- 3The ______ is 20,000 times smaller than the atom its selfNucleus
- 4Subatomic particles have very, very small masses and electrical charges. its more convenient to describe their masses and charges compared to a proton.These are called the particles relative mass and relative charge
- 5Proton has a relative mass of.... and a relative charge of...its relative mass is 1 and its relative charge is +1
- 6A neutron has a relative mass of.... and a relative charge of.....Its relative mass is 1 and its relative charge is 0
- 7an electron has a relative mass of.... and a relative charge of....Its relative mass is Negligible ( 1/1840) and its relative charge is - 1
- 8No two elements have the same number of...protons in their atoms

- Starting to create flash cards for the Edexcel's additional chemistry topics. Starting with structure of an atom hope to end with C2.34 waste and profit.. Hope these flash cards help!
