Question

question 26 (1 point) daltons atomic theory, did not propose which of the following? i. atoms combine in whole number ratios to form chemical compounds ii. atoms have nucleus iii. atoms are the tiny particles of elements iv. atoms can have isotopes v. in chemical reactions atoms combined, separated or rearranged 1) ii and iv 2) i, iv and v 3) i, iv and v 4) iv and v

Explanation:

Dalton's Atomic Theory proposed atoms combine in whole - number ratios (I), atoms are tiny particles of elements (III), and in chemical reactions atoms are combined, separated or rearranged (V). The concept of a nucleus in atoms was proposed later by Rutherford, and isotopes were discovered after Dalton. So II and IV were not part of Dalton's Atomic Theory.

Answer:

1. II and IV
