Explain why reactivity increases down group 1
WebGroup 1 - the alkali metals The group 1 elements are all soft, reactive metals with low melting points. They react with water to produce an alkaline metal hydroxide solution and hydrogen.... WebExplain why reactivity increases down group 2? because ionisation energy decreases meaning electrons are easier to remove so more reactive because increased atomic radius and increased shielding. What is the trend in solubility of the group 2 hydroxides? solubility increases down the group so the solutions contain more OH- ions and become ...

WebMay 14, 2024 · Explain why are the following statements not correct : (1)All groups contain metals and non-metals. (2)Atoms of elements in the same group have the same number of electron(s). (3)Non-metallic character decreases across a period with increase in atomic number. (4)Reactivity increases with atomic number in a group as well as in a … WebReactivity of halogens The non-metal elements in Group 7 – known as the halogens – get less reactive as you go down the group. This is the opposite trend to that seen in the alkali metals...
WebThe reactivity of Group 1 elements increases as you go down the group because: the atoms get larger. the outer electron gets further from the nucleus. the attraction between the nucleus and outer... WebFirst ionization energy decreases down group 1. Which statement is correct? A. Atomic radius decreases down group 17. B. First ionization energy decreases down group 1. C. Atomic radius increases across period 3 from Na to Cl. D. First ionization energy decreases across period 3 from Na to Cl. D Which increase across a period from left to right?
WebThe reactivity of Group 1 elements increases as you go down the group because: the atoms get larger. the outer electron gets further from the nucleus. the attraction between the nucleus and outer electron gets weaker – so the electron is more easily lost. WebJul 12, 2024 · The other hydroxides in the group are even more soluble. Solubility of the hydroxides increases down Group 1. In Group 2, the most soluble is barium hydroxide—it is only possible to make a solution of concentration around 3.9 g per 100 g of water at the same temperature of 20°C. It is difficult to explain the trends in solubility.
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.
