Atoms and Elements

An atom is the smallest thing discovered it contains electrons (which has a negative charge) neutrons (which has no charge) and protons (which has a positive charge).

An element is a substance which only contains one atom e.g gold only contains one atom which is gold atom. But all elements have different properties like copper is a soft beady metal and oxygen is a colour-less gas. All the elements on the left hand side of the periodic table are metals while elements on the right side of the  periodic table are none metals.

Mendeleev created the periodic table. The vertical columns are are called groups and the horizontal rows are called periods, all groups have different proprieties like group 1. has all shiny metals that react with water.

Illegal drugs are addictive,  dangerous and life wrecking.

space

 

space is surrounding the earth. High above the atmosphere of the earth, there is an entire new world to explore such as planets,stars,solar systems and even galaxies. They all make up what we call the universe  which remains unexplored until this second. All of this started with a theory called the big bang. Although space is largely empty even though it contains planets, stars and galaxies.

A planet is an object that orbits

#around a star.Among our solar system there is a planet called  earth, it has a inner core, outer core, mantle and the crust. The Earth came from a cloud in space which was made from a large amount of dust and gas. Earth was formed over billions of years ago, this dust whizzed around the sun and joined together to form lumps of rocks which then crashed into each other to form planets of like planet earth.                                               Image result for big bang explosion

The sun is part of a huge family of stars called the milky way which is our galaxy. Billions of stars combine together to make a galaxy. there are different forms of galaxies eliptical,spiral with a bar across the middle, spiral and irregular.
