If two elements A and B combine to form more than one compound, the masses of B that can combine with a given mass of A are in the ratio of small whole numbers. Dalton's Atomic Theory 1) elements are composed of atoms. 2) atoms of same element are identical, but differ from other...
‘atoms’. Atoms of the same element are identical... each element is unique Atoms of different elements can physically mix or chemically combine (compounds). Chemical reactions occur when atoms are separated, joined, or rearranged. Much of this theory is still accepted, ….. with 2 ...

1. Isopes are the atoms of the same element having same atomic number but different mass - numbers . 2. Isobars are the atoms of different elements having different atomic number of different atomic number but same mass - number .
atoms of the same element w/different #s of neutrons are called isotopes. in order to know how many neutrons in an atom you must be told. the mass number tells you how much mass t 13、he atom has. since p+ and n0 are the heavy parts, mass # = # of p+s + n0s.question: if...
