Last Answer : (4) Conversion of mass into energy

The enormous amount of energy released in an explosion of an atomic bomb is due to the - (1) conversion of mass into energy (2) conversion of chemical energy into heat energy (3) conversion of mechnical energy into nuclear energy (4) conversion of neutrons into protons

Description : The enormous amount of energy released in an explosion of an atomic bomb is due to the - (1) conversion of mass into energy (2) conversion of chemical energy into heat energy (3) conversion of mechnical energy into nuclear energy (4) conversion of neutrons into protons

Last Answer : (4) conversion of neutrons into protons Explanation: The enormous amount of energy released in an explosion of an atomic bomb is due to the converson of neutrons into protons. When, a neutron strikes ... , each of which is a nucleus with about half the protons and neutrons of the original nucleus.

The mass number of a nucleus is – (1) always less than its atomic number (2) always more than its atomic number (3) always equal to its atomic number (4) sometimes more - and somtimes equal to its atomic number

Description : The mass number of a nucleus is – (1) always less than its atomic number (2) always more than its atomic number (3) always equal to its atomic number (4) sometimes more - and somtimes equal to its atomic number

Last Answer : (4) sometimes more - and somtimes equal to its atomic number Explanation: Mass number = protons or mass of electron (atomic number) + neutrons. So it is mostly greater than the atomic number. At best, it can be equal to the atomic number.

An atom of an element has atomic number 17 and mass number 36. The number of neutrons in its nucleus is– (1) 17 (2) 19 (3) 36 (4) 53

Description : An atom of an element has atomic number 17 and mass number 36. The number of neutrons in its nucleus is– (1) 17 (2) 19 (3) 36 (4) 53

Last Answer : (2) 19 Explanation: Mass Number = number of protons (atomic number) + nu.sriber of neutrons. So as per the question, 36= number of neutrons + 17. Number of neutrons= 36 -17= 19
