More Hydrogen bubbles were forming than the elements above in that certain group ie: Ca reacted more than Mg.]]> 2018-03-06 18:17:05 UTC https://padlet.com/radcock/kdbkvirwdie7/wish/238793684 https://padlet.com/radcock/kdbkvirwdie7/wish/238794064 The trend for reactivity of metals down a group increases because as you go down a group the reaction of the elements gets more violent. When we tested Potassium we saw that there was a purple flame and many bubbles, but with Magnesium we saw that there weren't as many bubbles and not that big of a reaction. This trend occurs because of ionization energy. Metals usually donates electrons in order to be more like a noble gas and with ionization energy it is the amount of energy needed to remove electrons . Lower ionization energy means higher reactivity so going down a period causes the element to be more reactive.]]> 2018-03-06 18:17:42 UTC https://padlet.com/radcock/kdbkvirwdie7/wish/238794064 https://padlet.com/radcock/kdbkvirwdie7/wish/238794574 Reactivity increases down groups, because as you go down a group the number of electrons increase its easier for the electrons to be taken away or given away to other elements leading to higher reactivity.  ]]> 2018-03-06 18:18:28 UTC https://padlet.com/radcock/kdbkvirwdie7/wish/238794574 https://padlet.com/radcock/kdbkvirwdie7/wish/238794671 Reactivity increases down a group because of more ionization energy]]> 2018-03-06 18:18:37 UTC https://padlet.com/radcock/kdbkvirwdie7/wish/238794671 https://padlet.com/radcock/kdbkvirwdie7/wish/238794689 Reactivity for metals in a group increase going down because the farther down a roup of metals you go, the easier it is for electrons to be given or taken away, resulting in higher reactivity.

The trends are there because of ionization energy.

An example of this is calcium reacting with water versus magnesium reacting with water. Magnesium is higher in the group than Calcium, and when reacted with water, the reaction time is slower compared to Calcium's reaction time with water.]]> 2018-03-06 18:23:07 UTC https://padlet.com/radcock/kdbkvirwdie7/wish/238797877 https://padlet.com/radcock/kdbkvirwdie7/wish/238798504 the reactivity increase as we go down in the periodic table
