Alakaline Metals- 2

Read the responses from your classmates.

Using information from all of these comments, write a statement which you think best describes the relationship between these alkaline metals and their relative positions on the periodic table?

I think the statment which best describes the relationship between the alkaline metals is that they are all explosive when in contact with water. Their position on the periodic table shows that each of the alkiline metals get more and more reactive [with]the h20 moving down the column. Meaning hrydrogen is the least reactive of the metals, and Francium is the most explosive when in contact with h20.

The relationships between these two alkaline metals are that they both produce a medium to large explosion when placed into water, and both destroyed the bath in the braniac video in some way. I think the two alkaline metals would be on the left hand side of the periodic table because in class we were learning about how the more reactive substances on the periodic table are on the left hand side.

The relationships between these metals are similar, in the form of their reactions when combined with water, but the degree in which they explode varies. The most explosive/ reactive metals are positioned to the lower left of the periodic table. The table then decreases in reactivity as it spreads further to the right.

(sorry i didn’t really understand the question)

The further you go down the periodic table vertically the more violent and explosive the metals are.

The relationships between these Alkaline Metals is that they all are reactive when they come in contact with H20. but the reactions differ. the further you go down the periodic table on that line of Alkaline Metals, the more reactive you get. for example, a small amount of Caesium can cause a very large explosion.

the realtionship between these metals is that they all explode when placed in water but the the explosion gets bigger each time you go down the periodic table. When an alkaline metal is placed in water it nrelease the hydrogen gas from the water and explodes just like a hydrogen bomb

I think the relationships between the metals are that they both produce explosions when placed in water and but6 the extent of the explosion varies down the chart. As the elements get furhter down the chart, the explosions get stronger.

One simularitie between these metals is that they explode when they come into contact with water. The size of the explosion increases down the colum of the periotic tables.
