These breeds are intelligent and capable. They also has an aloof and sometimes suspicious nature — great for a watchdog.
The link with Elements are that…
Elements can wear 2 different hats!
Something to note: Elements are divided into metals and non-metals
The big divide can be seen in the periodic table – which lists all the elements in the world!
Yet reading a periodic table takes some skill because every element has a special number attached to it.
Just like soccer players, atoms of different elements have one special number…
This special number is the:
The number of protons is very very special because each element has its own unique number of protons.
For example, see nitrogen below, atoms of nitrogen have 7 protons. No other atoms have 7 protons, otherwise they will definitely be atoms of nitrogen.
Important point: each element has its own number of protons
The periodic table from left to right is arranged in accordance to proton numbers.
Notice how Nitrogen with 7 protons in its atoms is arranged beside Oxygen which has 8 protons in its atoms and Carbon, which has 6:
Take note: periods of periodic table arranged according to proton number
Besides being grouped into metallic or non-metallic elements, some groups of elements have very interesting properties:
A certain group of metals react vigorously or even explosively with cold water!
Watch this very cool video below!!!
Notice that this group of metals stick together down vertically?
This is no accident!
