00:00Chapter Nuclear Physics
00:01Question Number 3 is Find the Binding Energy
00:05in Mega Electron World for Lithium
00:08Now, atomic mass lithium
00:09can be found in Del M.
00:12Binding energy
00:13I don't know how much
00:15atomic number lithium
00:15is 3
00:17atomic mass
00:19lithium is 7
00:21neutron is 7
00:22neutron is 7
00:24minus 3
00:264
00:26mass of proton is 1.0073 AMU
00:31mass of neutron is 1.0087 AMU
00:36mass of lithium
00:37is 7.016003 AMU
00:40this is all
00:41so first of all, proton is 3
00:45proton is 3
00:46proton is 3
00:47neutron is 4
00:49and 4 is 4
00:49and they will plus them
00:52because
00:537.0567
00:557
00:55now
00:56proton and neutron
00:58is 1.0077 AMU
00:59mass defect
00:59is 1.007 AMU
01:01mass defect
01:02for mass of lithium
01:03we have to ask
01:04that question is minus
01:05this mass defect
01:07will be minus
01:08931.5
01:10we will multiply
01:11this
01:11binding energy
01:13which is
01:14which is
01:14which is
01:14which is
01:16the
01:16question
01:17number
01:173
01:17that
01:17the
01:17the
01:17and the
01:17the
