Answer is: <span>daughter nucleus is zinc.
</span>Nuclear reaction 3: ⁶⁴Cu → ⁶⁴Zn + e⁻ + electron antineutrino.<span>
Beta decay is radioactive decay in
which a beta ray and a neutrino are emitted from
an atomic nucleus.
There are two types of beta decay: beta minus and beta
plus.
In beta minus decay, neutron is converted to a proton and
an electron and an electron antineutrino and </span><span>atomic number Z is increased by one</span>.
Answer:
The elements on the left-side of the periodic table are relatively electron deficient. So due to their comparatively low effective nuclear charges (the net positive charge of the protons minus the shielding core electrons below the valence level), their electrostatic hold on these electrons are weak.
Elements further right on the period table though, have higher effective nuclear charges and stabilize electrons more effectively. Which leads to localized covalent bonding and the formation of molecules.
The right side contains non metals while the left side contains metals.
Metals lose electrons (negative electrons). They now have more protons, therefore making the ion positive.
Non metals gain electrons (positive electrons). So the ion has more electrons than protons which makes the ion negative.
1. Radio isotopes are used in all the industries mentioned above, that is, nuclear power plants, pharmacology and agricultural studies. So the correct option is D.
2. The statement is true. Radio isotope is used in medicine mostly as a diagnostic tool to diagnose illnesses.
3. Nuclear wastes are enclosed in lead and buried in cement casks deep underground so that the lead, cement and the earth cover will act as radiation shield. The correct option is B.
4.This statement is false. The US has 75 different radioactive storage locations across USA.
5. This statement is false. Radioactive contamination can enter the body through inhalation, ingestion, absorption and through contact with skin or clothing materials.
6. The statement is false. Uranium fuel is not burned, it undergoes fission process.
7. This statement is true. This is because nuclear power production has less green house effects compare to fossils fuels.
8. This statement is false. Nuclear energy is not renewable and it pollutes the environment.
9. Nuclear power plants are favoured because the power produce by them are more reliable source of energy which does not deplete the ozone layer.
