An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element.
2. J.J Thomson
3. 1897
4. In electrons
5. They are important because we need to know about elements and which ones can be potentially dangerous.]]> 2019-01-08 22:03:01 UTC https://padlet.com/508337/s0h1l16d4htt/wish/318589623 52109 https://padlet.com/508337/s0h1l16d4htt/wish/318589879 1. what is an atom?
a. /ˈadəm/ (noun): the basic unit of a chemical element.

2. who discovered the atom?
a. john dalton, j. j thompson, and ernest rutherford.

3. when was it discovered?
a. 1897 (a major advance in time)

4. where was it discovered?
a. it was discovered when rutherford was looking at electrons. he found a nuclear atom in the gold foil experiment.

5. why is it important for us to know about the atom?
a. "The fact that atoms cannot be created or destroyed in chemical reactions allows for all sorts of important predictions.

An atom is a fundamental piece of matter.( Matter is anything that can be touched physically.)

2. John Dalton
3. They were discovered in 1897.
4. Atom was the discovery of electrons. 

5. Why is it important for us to know about the atom?
The food you eat, the air we breathe even your body is made up of matter. All the "stuff around us is made of matter. But matter is made up of atoms. From the trees to the bees: Humans , water, air, food- it's all made up of atoms. ]]> 2019-01-08 22:04:53 UTC https://padlet.com/508337/s0h1l16d4htt/wish/318590086 507133 https://padlet.com/508337/s0h1l16d4htt/wish/318590380 1. An atom is an extremely small amount of a thing or quality.
2. J.J. thomson
3. The atom was first discovered in 1897
4. Cheetham Hill, Cambridge
5. Atoms form the smallest building blocks of chemistry, and they combine to form an infinite variety of more complicated structures.
