Mammoth Memory

Groups of the periodic table

All of the elements in the periodic table are divided up into groups. All of the elements in a group behave in the same way. They have some pretty weird names, though, which are very difficult to remember… unless you use the Mammoth Memory story technique, of course!

 

We were talking about groups, which is a coincidence – I was out for a walk with a group of friends just the other day. Begin story!

1.    Alkali metals

Group 1 contains alkali metals such as potassium and sodium
We were all very nervous because we had to go down a back street full of drunks, all the alkies were lying down.(Alkali metals)

Never call this group just alkalis, it should always be referred to as the alkali metals. Alkalis on their own are something entirely different. See our Acids and Alkalis section.

 

2.    Alkaline earth metals

The alkali earth metal group contains elements such as magnesium and calcium
Looking down, I saw that the street itself was paved with bottles and cans of alcohol in lines in the earth. (Alkaline earth)

 

Never call this group just the alkalines; these elements should always be referred to as the alkaline earth metals. The word alkaline refers to something entirely different. See our Acids and Alkalis section.

3.    Transition metals

The transition metal group contains elements such as gold and Iron
We were so worried about walking that we drove through instead, in a transit van. (Transition metals)

 

4.    Icosagens

The icosagens group also known as the boron group contains elements such as boron and aluminium

We drove safely out of the alley and a very expensive jewellery store caught my eye – it was selling high cost gems. (Icosagens

 

5.    Crystallogens

The Crystallogens group also known as the carbon group contain elements such as carbon and lead
The most impressive thing they were selling was a glittering necklace made of crystal. (Crystallogens)

 

6.    Pnictogens

The Pnictogens group also known as the nitrogen family contain elements such like nitrogen and Arsenic
But, as I watched, thieves suddenly ran up and smashed the glass! The necklace quickly got nicked! (Pnictogens)

 

7.    Chalcogens

The Chalcogen group also known as  the oxygen family contains elements such as oxygen and Sulphur
I could see the poor store owner inside, adding up what had been taken on his calculator. (Chalcogens)

 

8.    Halogens

The Halogen group contains elements such as chlorine and bromine
What happened next was incredible! An angel swooped down and caught one of the thieves by snaring him with her halo! (Halogens)

 

9.    Noble gases

The noble gas group contains elements such as Helium and Neon

The angel presented the thief she had caught to the mayor. His clothes made him look very noble. (Noble gases)
