Most active to least active elements
WebApr 7, 2024 · It is also known as activity series. The reactivity of metals is because of their incomplete outer orbitals or due to their electronic configuration. Metals form positively charged ions as they tend to lose electrons. Metals with high atomic numbers tend to be more reactive as their electrons are far from the positively charged nucleus, so ... Weba) All atoms of a given element have the same mass. b) Avogadro's number is the number of atoms in exactly 12 grams of Carbon- 12. c) The electron and the proton have charges equal in magnitude and opposite in sign. d) The mass number is the total number of protons and neutrons in the nucleus. 31. The valence electrons of an atom, "E", are ns 2 ...

WebAnswer (1 of 7): Reactivity of halogens decreases on moving down the group because on moving down, the size increases and it becomes difficult for the element to gain electron hence reactivity decreases. On this basis ,order of reactivity will be- Flourine > Chlorine > Bromine > Iodine > Astatine.
