The cards Question In what order are the elements listed in the periodic table? Tap to flip Answer In order of increasing atomic number. Question What is a vertical column of the periodic table called? Tap to flip Answer A group. Question What is a horizontal row of the periodic table called? Tap to flip Answer A period. Question What does the group of an element correspond to? Tap to flip Answer The number of electrons in the outer shell of its atoms. Question What does the period of an element correspond to? Tap to flip Answer The number of electron shells in its atoms. Question Which Russian scientist developed the periodic table? Tap to flip Answer Dimitri Mendeleev. Question Where in the periodic table are the transition metals found? Tap to flip Answer In the central block. Question Do elements in the same group or in the same period have similar properties? Tap to flip Answer Elements in the same group; properties vary across a period. Question How do the properties of elements in a group of the periodic table change down the group? Tap to flip Answer They change gradually. Question Give one physical property of the Group 1 metals. Tap to flip Answer e.g. they are soft, or they have lower densities than most other metals. Question How does the reactivity of Group 1 metals change down the group? Tap to flip Answer It increases. Question Why are Group 1 metals called the alkali metals? Tap to flip Answer Because they react with water to form an alkaline solution. Question Which gas forms when a Group 1 metal reacts with water? Tap to flip Answer Hydrogen. Question What two products form when a Group 2 metal reacts with a dilute acid? Tap to flip Answer A salt and hydrogen gas. Question How does the reactivity of Group 2 metals change down the group? Tap to flip Answer It increases. Question Is a Group 2 metal more or less reactive than the Group 1 metal in the same period? Tap to flip Answer Less reactive. Question What is an alkali? Tap to flip Answer A soluble base with a pH greater than 7. Question Which group of the periodic table are the halogens in? Tap to flip Answer Group 7. Question Are the Group 7 elements metals or non-metals? Tap to flip Answer Non-metals. Question Are the vapours of the Group 7 elements coloured or colourless? Tap to flip Answer Coloured. Question How does the state at room temperature of the Group 7 elements change down the group? Tap to flip Answer It changes from gas to solid. Question What is the state of bromine at room temperature? Tap to flip Answer Liquid. Question What is the state of iodine at room temperature? Tap to flip Answer Solid. Question How does reactivity change down Group 7? Tap to flip Answer It decreases. Question What type of compound forms when a halogen reacts with a Group 1 or Group 2 metal? Tap to flip Answer A metal halide. Question What is a halide? Tap to flip Answer A salt formed from a halogen and another element, e.g. sodium chloride (NaCl). Question Are metal halides soluble in water? Tap to flip Answer Yes. Question What is a salt? Tap to flip Answer A substance formed when a metal reacts with a non-metal. Question Give one example of a useful compound that halogens form. Tap to flip Answer e.g. table salt or disinfectants. Question Which group of the periodic table are the noble gases in? Tap to flip Answer Group 0. Question What is the state of the noble gases at room temperature? Tap to flip Answer They are all gases. Question Why are the noble gases stable and unreactive? Tap to flip Answer Their atoms have complete outer electron shells. Question What does 'inert' mean? Tap to flip Answer Not chemically reactive. Question Give one property that increases down Group 0. Tap to flip Answer e.g. atomic mass, density or boiling point. Question What does the word 'noble' in 'noble gases' refer to? Tap to flip Answer Their stability and lack of reactivity.

How this deck was checked On 2026-11-02, every card was compared with its source: the lessons of Oak National Academy, a public body funded by England's Department for Education that publishes lessons for the national curriculum. Because the cards come from those lessons, no second source was sought. The comparison was done automatically, not by a teacher, so a card can still be wrong.
