Because of the structure of the electron cloud, as particles were radiated onto a gold atom, what was observed during rutherford's experiment? a. electron cloud absorbed the particlesb. particles that struck the nucleus went straightc. particles that struck the nucleus are absorbedd. electron cloud allowed the particles to pass through

(d) Electron cloud allowed the particles to pass through

Explanation:

Rutherford observed that, unexpectedly, most alpha particles went through the plate following an almost straight path (passing through). Only a few that struck the relatively small but massive nucleus were deflected at large angles.

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases . this process does not change the mass number.

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as -decay. in this the mass number remains same.

from the above information, we see that only alpha-decay is producing a change in the mass number of the nucleus.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
