Hey kids ! Today I'm going to introduceyou to the world of atoms . Atoms areLittle Things That you or anybody else have ever seen .Make up things like trees , cars , paper , even you.So let's shrink down to size and see what it's like .
We're going to into the helium atom today .An atom is made of little things called protons , nuetrons , andelectrons . Protons have a positive charge , neutrons have no charge ,and electrons have a negative charge . Electrons travel around the center ofthe atom , Which is called the nucleus . Kind of like how Earth revolves around the sun .Protons and nuetrons make up the center of the atom .
The atom has an atomic number . Scientists Find That number by counting how manyprotons are in the nucleus . In this case Helium has two protons .
Scientists find the average atomic mass by adding up protons and neutrons many times .Then they divide the total by how many times they tried this . This time Helium hasan average of four protons and neutrons in the center .
The electron arrangement is the number of electrons in each ring or shell .In this case helium has 1 ring with two electrons in it . An aatom can have up toonly 7 rings .
An atomic symbol is the letter (s ) That describe the element . Like He meanshelium , but if you wrote it HE it could mean something totally different so becareful .
An isotope has more neutrons than protons or Fewer .So there is not the same number of protons as neutrons .
Well now that I'm big again I hope you learned everythingyou wanted to know about atoms .
