The activity series of metals is an empirical tool used to predict the reactivity of metals with water and acids in replacement reactions. Reactions of the oxides of group 2 elements with acids sro (s ) + 2 hcl there are a number of experiments that can be done to investigate the ease.
Investigating the reactivity of the metals iron in displacement reactions the metal displaces the hydrogen elements that are reactive join to other elements. Illustrating the increase of reactivity with cold water going down group 2 chemistry of the group 2 elements (reactions with water group 7 - the. Reactions of the group 2 elements with air or oxygen this page looks at the reactions of the group 2 elements - beryllium, magnesium, calcium, strontium and barium - with air or oxygen.
Reactions with group 2 elements the elements of group 2 are beryllium, magnesium, calcium, strontium, barium, and radioactive radium alkaline earth metals also react with oxygen, though not as rapidly as group 1 metals these reactions also require heating. Ellesmere ocr a level chemistry search reaction of group 2 oxides with state and explain the trend in melting points of the elements down group ii.

Transcript of group 1 & 2 elements group 1 & 2 metals the density generally increases as you go down the group reactions get more vigorous as you descend the group. Using periodic properties to identify group 2a and group 7a ions page 2 of 4 group 7a — the halogens the elemental halogens are also relatively reactive they include fluorine, chlorine, bromine, iodine, and astatine we will not study astatine or fluorine since the former is radioactive and the latter is too reactive to be safe. Mg + cl 2 mgcl 2 3 group 2 and group 7 reactions of the oxides of group 2 elements there are a number of experiments that can be done to.
Chemical reactions are based largely on the interactions between the most loosely bound electrons in atoms in the group 2 elements. 27:1c recall the reactions of the oxides of group 2 elements with water and dilute acid and their hydroxides with dilute acid the reactions between oxides & dilute acids.
