Element X is below element Y in the same non-metallic group of the periodic table Aelement X will be more reactive than element YBelement X will be more electronegative than element YCelement Y will be a stronger oxidising agent than element XDboth elements X and Y will form covalent compounds only

Compared to group 2 elements, group 1 elements:Group of answer choicesAre less reactiveHave smaller atomic radiusHave more valence electronsAre more reactive

Metal X forms an oxide that reacts with acids but not with strong alkalis .  Metal y forms an oxide that reacts with acids and strong alkalisMetal Z forms a hydroxide that is not decomposed by heating Which combination BEST identifies X , Y and Z ? AX= calcium , Y = zinc , Z = magnesium BX= iron , Y = aluminium , Z = sodiumCX= aluminium , Y = sodium, Z = calcium DX= magnesium , Y = copper , Z = potassium

When non-metals react with metals, the non-metalAbehaves as a reducing agentBremoves electrons from the metal atoms Ccan form both ionic and covalent compounds Dcause the oxidation number of the metal to decrease

Metal X burns vigorously when heated in air, whereas metal Y burns only when heated very strongly . Which of the following is the correct descending order of reactivity of Metal X , metal Y , copper and magnesium . AMagnesium, metal X, metal Y , copper  BMetal X , magnesium , copper , metal YCcopper , metal Y , Metal X , magnesium DMetal X, magnesium , metal Y , copper

1. Element X is a metal that reacts to form XCl. It has the smallest metallic radius of its group. What is element X?LiCsFrH
