What is the process by which anions are formed?
Electron gain by non-metal atoms
Match the following atoms with their resulting ions when they gain or lose electrons:
A chlorine atom that has gained 1 electron = Cl- anion A sodium atom that has lost 1 electron = Na+ cation A nitrogen atom that has gained 3 electrons = N3- anion An iron atom that has lost 2 electrons = Fe2+ cation
Match the following descriptions with the type of ion:
An ion that has lost electrons to become overall positively charged = Cation An ion that has gained electrons to become overall negatively charged = Anion An ion that has the same number of protons as electrons = Atom An ion that never forms at all = Noble gases
Match the following elements with the type of ions they can form:
Metals = Cations Non-metals = Anions Noble gases = Neither cations nor anions Hydrogen = Cations
Match the following electron configurations with the corresponding atom or ion:
2, 8, 1 = A sodium atom 2, 8 = A sodium ion 1, 2 = A hydrogen atom 1, 2, 3 = A nitrogen atom
Match the following processes with the type of ion formed:
Metal atom loses electrons = Cation Non-metal atom gains electrons = Anion Metal atom gains electrons = Anion Non-metal atom loses electrons = Cation
Match the elements with their respective atomic numbers:
Carbon = 6 Calcium = 20 Chlorine = 17 Copper = 29
Match the elements with their classification as metal or non-metal:
Fluorine = Non-metal Titanium = Metal Iodine = Non-metal Zinc = Metal
Match the ion formation processes with their descriptions:
Cation = An atom that has lost an electron Anion = An atom that has gained an electron Metals = Atoms that lose electrons Non-metals = Atoms that gain electrons
Match the elements with their atomic symbols:
Carbon = C Manganese = Mn Xenon = Xe Uranium = U
Match the elements with their special properties:
Hydrogen = Can both lose or gain an electron Metals = Typically lose electrons Non-metals = Typically gain electrons Noble Gases = Unreactive
