divided, or destroyed. Atoms of the same element are exactly alike, and atoms of different elements are different. Atoms join with other elements to make new substances. This was NOT ALL CORRECT!
It said four things: (1) All matter is made of atoms. (2) Atoms of an element are alike. (3) Atoms of different elements are different. (4) Atoms of different elements join together to make compounds. In the late 1800’s, J. J. Thomson discovered that atoms were made of smaller ...
Atoms of the same element are exactly alike. Dalton’s Model Basic Ideas of Dalton’s Atomic Theory (con’t) : C. Atoms of different elements are different. D. Compounds are formed by the joining of atoms of 2 or more elements. Foundation of modern chemistry Thomson’s Model J.J. ...
1815: English physician William Prout (1785–1850) suggested the weights of different elements are simple multiples of the weight of a hydrogen atom—not quite true, but another important clue to understanding how atoms are made. 1869: Building on the insights of Lavoisier, Dalton, Prout and ...

frpm.elements can be classified by there state (or phase )at room temperature.the state means whether the element is a solid.liquid or gas.substances which contain different elements are either mixtures or compounds.最好不要用翻译器.(现在我馍有财富值了.赚够多少一定全部抛出感谢)话是这样讲 可...
He believed that all matter was made of elements (元素),which he called atoms. This is where the word "atom" comes from. More about atoms: John Dalton An English chemist and physicist called John Dalton(1766-1844) found out that there are many different kinds of atoms. He drew pictures...
