Atomic Science: Periodic Table

 Kia ora everyone this past few lessons on science we were studying about the periodic table, elements, atoms, chemical and physical change, electrons, balancing symbol equations, mixture, and compounds, and chemical word equations. We also played Element Bingo.

The periodic table shows us all the elements and their physical properties, it is arranged base on atomic number and electron configuration. 

Alkaline Metals

Alkaline Earth Metals

The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium, magnesium, calcium, strontium, barium, and radium. The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure. They react to everything because their outer shell is unstable which means it only has 1 electron. Having 1 electron is easier to get rid of it rather than gaining 7 more, so it reacts to everything

Alkaline Metal Experiment

We also did an experiment about alkaline metals, but we only use Lithium (Li) and Sodium (Na). Ms put the Lithium onto the water and it bounces very fast which causes it to levitate while levitating there was smoke coming from the lithium, due to the reaction of the chemical and water. The lithium slowly dissolves (base on what I think) and shrank to the bottom of the container and started to dye the water, purple. 

The second one we did was Sodium (Na), this one was pretty entertaining and cool. Sodium is very reactive, it reacts to everything that's why it is covered with oil and put into a jar. It is a very soft metal so Ms just cut a small piece of it for the experiment. Same as what she did with the lithium, Ms put the sodium onto the water and it reacts as if it was lithium but our teacher told us that this isn't how it is gonna react to water. So she took a big piece of sodium and sliced off the sides that are covered with oil, she was left with a small piece of pure sodium the size of a peanut. She put it onto the water and a few seconds later, KABOOM! it exploded and smoke and small sparks of fire spread in the science room. 

Don't worry we're safe because there was this glass shield that was put in the front of the container to prevent us from getting harm, poor tables tho they got burnt marks from the fire and sparks. 

HAVE A GREAT DAY!...
