Explain why reactivity increases down group 1
WebThe reactivity of group 1 elements increases as you go down the group because: the atoms become larger the outer electron becomes further from the nucleus the force of … WebApr 9, 2024 · The periodic trend of atomic radius across a period – As we move from left to right in a period, atomic radius gradually decreases. Reason – As we move left to right in a period the atomic number of the elements increases so nuclear charge increases while the number of shells in elements remains the same. Example –.

WebAug 15, 2024 · Explaining the increase in reactivity down the group The reactions proceed faster as the energy needed to form positive ions falls. This is in part due to a … WebThe reactivity of group 1 metals increases as you go down the group because: 1) The atomic radius increases. The atom is held together by strong electrostatic forces of attraction between the positive protons in the nucleus and negative electrons. As you go down the group, the outer shell electron is further away from the positive nucleus.
WebWhy does reactivity increase going down group 1? (2). Because the atoms get larger, the single electron in the outermost shell gets less attracted to the nucleus. The electrostatic attraction with the nucleus gets weaker because the distance between the nucleus and the outermost electron increases ... How can you explain reactivity trends ...
