Answer: Hydrogen is diatomic.
Explanation:
Because hydrogen exists as a diatomic molecule.
D. Both particles and high energy radiation
The element sodium (Na) in the periodic table requires the least amount of energy to remove the most loosely held electron.
<h3>What is the trend of sodium?</h3>
The periodic table is the arrangement of the elements based on their physical and chemical properties.
The sodium element requires the minimum energy to eliminate the electron from its outer shell.
The sodium element has low nuclear energy and small size making the shielding effect to be negligible.
The loss of an electron from the outer shell results in the achievement of a stable configuration.
Thus, sodium requires the least energy.

Answer:
Yes because magnesium has a more negative reduction potential than aluminum.
Explanation:
The single factor that will determine whether a battery with magnesium as anode and aluminium as cathode will work or not is the respective electrode potentials of the two elements.
Recall that in a battery, oxidation occur at the anode and reduction occurs that the cathode. The reduction potential shows the ease with which a metal is reduced or oxidized. The substance with the most negative reduction potential will function as the anode while the substance with the less negative electrode potential will function as the anode.
The reduction potential of Magnesium is -2.37 V while that of aluminum is -1.66 V. This implies that magnesium must function as the anode and aluminum as the cathode in order to have a spontaneous electrochemical process in the cell.
Answer:
Metals , silver and copper which allows to pass the electricity through it is called good conductor of electricity .
