Cards in this deck (13)
- 1ionCharged particles which form when an atom loses and or gains electrons
- 2CationA positively charged ion, formed by losing electrons
- 3AnionA negatively charged ion , formed by gaining electrons
- 4ElementA pure substance that contains only one type of atom
- 5IsotopesDifferent forms of the same element which have the same number of protons but a different number of neutrons
- 6Mass numberThe number of protons and neutrons in the nucleus of an atom
- 7MoleculeA group of two or more atoms held together by chemical bonds
- 8CompoundTwo or more types of atoms chemically bonded together
- 9Atomic numberThe number of protons in the nucleus of an atom
- 10IsomerMolecules with the same molecular formula but a different arrangements of atoms
- 11Ionic bondingWhen two ions are attracted to each other, these ions are opposite (metal/nonmetal - Positive/negative), this is why they attract (Electron transfer)
- 12Covalent bondingWhen two nonmetals want to gain so they have to share the remaining electrons
- 13Metallic bondingHappens when a metal loses or discharges an electron, this is then transformed as electricity as the electrons are pushed, they don’t have anywhere to go they are delocalized.
