ARMRIT Study Guide Questions And Answers with Complete Solutions

Atoms - answer-fundamental submicroscopic unit of all mass. Size of the atom and its weight have interested scientists for a long period. Subsequently, experiments were devised to determine the size and weight of the various atoms. The lightest of all atoms is hydrogen. Proton - answer-a subatomic particle having a positvie charge identical in magnitude to the negative charge of an electron and, together with the neutron, a component of all atomic nuclei. The proton forms, by itslef, the nucl...

Proton - answer-a subatomic particle having a positvie charge identical in magnitude to the negative charge of an electron and, together with the neutron, a component of all atomic nuclei. The proton forms, by itslef, the nucleus of the hydrogen atom. The mass of a proton is approximately 1836 times that of an electron and the mass of an atom is contained almost entirely in the nucleus. The proton has an intrinsic angular momentum or spin and thus a magnetic moment (very small magnetic field). T...

magnetism - correct answer -property of matter that results from orbiting electrons in atoms - magnetic moments with angular momentum -field strengths measured in units of Gauss(G) and Tesla (T) - 1T= 10,000G - earth 0.5 G ferromagnetism - correct answer -contain iron, nickel or cobalt -large positive magnetic susceptibility -remain magnetized even when external magnetic field is removed -cause artifacts such as loss of signal and spatial distortion paramagnetism - correct answer - ...

SUBSEQUENTLY, EXPERIMENTS WERE DEVISED TO DETERMINE THE SIZE AND WEIGHT OF THE VARIOUS ATOMS. THE LIGHTEST OF ALL ATOMS IS HYDROGEN. PROTON - ANSWER-A SUBATOMIC PARTICLE HAVING A POSITVIE CHARGE IDENTICAL IN MAGNITUDE TO THE NEGATIVE CHARGE OF AN ELECTRON AND, TOGETHER WITH THE NEUTRON, A COMPONENT OF ALL ATOMIC NUCLEI. THE PROTON FORMS, BY ITSLEF, THE NUCL...
