Question 2 of 15 Incorrect Map Sapling Learning In the early 1800s an English school teacher, John Dalton, proposed six postulates on what an atom is. Dalton's theory was founded on very primitive experiments; however, several of the six postulates are regarded as true today. Sort the following six postulates Dalton proposed as accepted today or no longer accepted Accepted Today No Longer Accepted All matter is made of atoms In chemical reactions, atoms are combined, separated, or rearranged All atoms of a given element Atoms of different elements combine in simple are identical in mass and properties whole number ratios to form chemical compounds Atoms of different elements have different properties An atom cannot be created, divided, or destroyed Previous Give Up & View Solution Check Answer NexExit Hint

Explanation / Answer

ACCEPTED TODAY :

1.ALL MATTER IS MADE UP OF ATOMS : IN THIS STATEMENT DALTON ALSO STATED THAT ALL MATTER IS MADE UP OF INDIVISIBLE PARTICLE KNOWN AS ATOMS, SO THIS WOULD BE WRONG , BUT , NOW AS RIGHT NOW YOU JUST HAVE THE STATEMENT THAT ALL MATER IS MADE UP OF ATOMS IT IS CORRECT.

2. ATOMS OF DIFFERENT ELEMENTS COMBINE IN SIMPLE WHOLE NUMBER TO FORM CHEMICAL COMPONDS

3. ATOMS OF DIFFERENT ELEMENTS HAVE DIFFERENT PROPERTIES : ALTHOUGH THERE MAY BE SOME SIMILAR PROPERTIES BUT THEY ARE NOT COMPLETELY IDENTICAL

4. IN CHEMICAL REACTIONS ATOMS ARE COMBINED SEPERATED AND REARRANGED : ANY CHEMICAL REACTION IS A RESULT OF THIS POSTULATE

NO LONGER ACCEPTED

1. AN ATOM CANNOT BE CREATED DIVIDED OR DESTROYED : ATOMS CAN BE DIVIDE IN ELECTRONS PROTONS ETC.

2. ALL ATOMS OF GIVEN ELEMENT ARE IDENTICAL IN MASS AND PROPERTIES : THIS IS WRONG AS YOU KNOW THAT ISOTOPES EXIST IN NATURE
