What is the Trend for the Reactivity of Metals? Why does this Trend Exist? What Evidence do you have for this Trend? by Rebecca Adcock https://padlet.com/radcock/mgwupn7b4as1 Please answer all parts of the question with either a video or words that can be shared with the class. en-us 2018-03-05 17:37:56 UTC 2018-03-06 17:49:13 UTC hello@padlet.com 1.What is the Trend for the Reactivity of Metals. 2.Why does this Trend Exist? https://padlet.com/radcock/mgwupn7b4as1/wish/238716884 1. It Increases, Left---->Right because of its electronnegativaty 2.Its caused by the increased of protons and electrons across on period.

On the periodic table from left the right it decreases,and Up & down increases.

This is because lower ionization energy makes it easier to lose electrons. This was demonstrated in our lab yesterday when the acidity increased down the periodic table.

The reactivity of metals increases as you go down. This is true because metals have low ionization energy. This means its easier to lose electrons.
This was seen in the demo when there was a bigger reaction each time because we kept going down the group.

Increases down a group because the metals have more electrons taken away. Evidence for this trend is when you measure pH levels.

As the atom gets larger the electrons are pushed further out and the attraction between the nucleus and electrons grow weaker making it easier to lose an electron

The atom gets larger (atomic radius) going down a group and the outer shell  expands further from the nucleus. The attraction (electronegativity) between the nucleus and the electrons become weaker, so an electron is less likely to be gained. As the electronegativity decreases, so does the ionization energy using less energy making it easier to lose an electron]]> 2018-03-06 16:38:06 UTC https://padlet.com/radcock/mgwupn7b4as1/wish/238720866 Metals decrease down a group .

It decreases from left to right and increases as you go down. 

It decreases across a period and increases down a group. This is exists because it is used to find the final product. 

The ionization between the nucleus which then created the electrons to become weaker which is meaning an electron is less likely to be gained. When you measure the pH levels, it shows the evidence for the trend because we used both Mg]]> 2018-03-06 16:42:52 UTC https://padlet.com/radcock/mgwupn7b4as1/wish/238724417 https://padlet.com/radcock/mgwupn7b4as1/wish/238738481 2018-03-06 17:01:56 UTC https://padlet.com/radcock/mgwupn7b4as1/wish/238738481
