- 1What is atomAtom are different material are made up of tiny building blocks
- 2What is mass numberThe number of proton and neutron in an atom
- 3What is molecular element made upIs made up of small molecules like the oxygen,phosphorus and sulfur molecules
- 4Why is cabon is a unique elementBecause carbon atom can form extremely large molecules
- 5Is it true/false carbon is the only non-metallic elements that can form crystal latticesTrue
- 6Is it true/false that not many coumpoud form crystal latticesFalse many coumpoud form crystal lattices
- 7What happened when u have positive chargeIt gives u (+1)
- 8What happened when u have negative chargeIt give u (-1)
- 9What is atomic numberThe number of proton In a nucleus the atomic number determines what type of atom it is
- 10What is ionAn atom that has gained or lost an election
- 11What happened when proton is more then electionIt will be positive charge
- 12What do u call it when election is more the proton and is it positive or negativeIt called anion and its negative
- 13Is it true/false that the symbol for an ion is the same as the chemical symbol for the atomTrue
- 14What the proton number in the nucleus11 proton in the nucleus
- 15What's the number of electron spinning In a cloud around the nucleus11 electron spinning in a cloud around the nucleus
- 16What's the number of neutron In the nucleusThe mass number is 23
And the atomic number is 11
23-11=12
So there are 12 neutron in the nucleus - 17Subatomic particlesIs the particles that atom are made of proton,neutron and electron
