Exploring Molecular Shapes

1. The question we had in this lab was, How does the number of things around the central atom affect the shape of a molecule? We wanted to answer this because not all molecules have the same shape.

2. During our experiment we checked how the shape of molecules changed when we added bonding pairs or lone pair electrons. We noticed that when we added a another bonding pair to the molecule the angles between the pairs decreased. The less bonding pairs they had, the bigger the angles would be.

3. So our claim ended up being " The number of things around a central atom changes the shape of the molecule because of vesper".Our evidence came up with how many bonding pairs we put on a molecule as well as lone pair electrons. With two bonding pairs the angle would be 180 degrees. Add one more and it would go to 120, 4 bonding pairs and it makes 109 degrees, 5 bonding pairs and it would be 90 degrees, and lastly  bonding pairs make it go to 90 degrees. In the other hand adding more than two lone pair electrons the angles end up growing bigger. So we ended up seeing that vesper make valance electrons to repel each other as far as possible because they are the same charge. We also saw that bonding atoms and lone pairs do affect the shape of the atom because how with enough lone pairs and the angles between bonding atoms increases.

Exploring Reactivity and Periodicity Lab

So in chmistry class we did a lab and the Question was Is reactivity a periodic property? So the elements and things we used we're Sodium, Magnesium, Potassium, Copper, Calcium, and Phenomenological. So in this lab we got some water in two beakers and three test tubes. We put Sodium and Potassium in the beakers. When Sodium was added the reactivity was sudden and it ran on top of the water. The Potassium in other hand burst into a flame . In the other three beakers we put Calcium, Magnesium, and Copper. Calcium had turned the water pink and then gassed up. Magnesium turned the water foggy and then the piece of Magnesium had turned pink. Copper ad only turned foggy. So because the periodic table is periodic we can see a pattern with the elements in reactivity from up to down and left to right in decreasing order. So like Potassium was more reactive than Calcium because the potassium showed more reactivity than Calcium. So like Potassium is is lower than Calcium in the peri

What I learned this week, 3 Questions blog. Chemistry

The task's I've learned this week was the scientific numbers, well like a refresh from it but this time it sounds more clear. Something I've learned recently was the chemical reactions like if they are either physical or chemical reactions. Next time I go to class I will try to understand everything so I can do things without doubting myself.
