Answers
Answer:
metals-e.g: iron,gold
compounds-H2O [water],NaCl [salt]
non-metals -wood,glass
elements- Hydrogen[H],oxygen[O]
metalloids-silicon[Si] ,Boron[B]
radioactive elements-Uranium[U] ,Radium[Ra]
natural elements-water,wind
diatomic gases-hydrogen[H], nitrogen[N]
polyatomic molecules-sulphuric acid[H2SO4] - totally 7 atoms ,Hexane[C8H14]
Answer:
1) METALS :- iron , copper
2) COMPOUND :- water-formula : H₂O = hydrogen₂+ oxygen , salt-formula : NaCl = sodium+chlorine
3) NON-METALS :- oxygen , carbon
4) ELEMENTS :- silver , gold
5) METALLOIDS :- boron , silicon
6) RADIOACTIVE ELEMENTS :- uranium , radium
7) NATURAL ELEMENTS :- hydrogen , carbon
8) DIATOMIC GASES :- hydrogen-H , nitrogen-N
9) POLYATOMIC MOLECULES :- carbon dioxide , sulphur dioxide
