Order the sequence of ideas that led to the current model of the atom. place a number in front of each event to show the correct order. rutherford discovered that atoms have a nucleus. dalton developed the theory that all matter is made of atoms. schrödinger developed the electron cloud model of the atom. bohr developed the model in which electrons orbit the nucleus. thomson discovered that atoms contain electrons.

3 Rutherford discovered that atoms have a nucleus.

1 Dalton developed the theory that all matter is made of atoms.

5 Schrödinger developed the electron cloud model of the atom.

4 Bohr developed the model in which electrons orbit the nucleus.

2 Thomson discovered that atoms contain electrons.

it is a good conductor

explanation:

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
