The number following the name of the element is the number of subatomic particles inside the nucleus of the atom. This means that it is the mass number of the isotope. The average atomic mass of the element is the sum of the products of the percentage abundance and mass number of the naturally occurring isotopes.
Since, the average atomic mass of the hydrogen is nearest to 1 then, the most abundant isotope should be hydrogen-1.
Protons .because electron has negative charge and proton has positive charge.
Mercury and carbon two electrodes can't be used with an inactive or inert material.
<h3>What is an electrode?</h3>
The electrode is the element which is used to complete the electric circuit in welding. Some time electrode is connected with the positive terminal and sometimes with a negative terminal, it depends on the requirement of the welding process.
Inert electrode is an electrode that serves only as a source or sink for electrons without playing a chemical role in the electrode reaction. Precious metals, mercury, and carbon are typically used as inert electrodes.
Therefore, neither of the two electrodes can be used with an inactive or inert material.

Answer: Nuclear energy is by far the safest energy source in this comparison – it results in more than 442 times fewer deaths than the 'dirtiest' forms of coal; 330 times fewer than coal; 250 times less than oil; and 38 times fewer than gas.
Answer:
Explanation:
The three of them increase from left to right across the periods of the periodic table, and at the same time, they decrease from up to down across the groups of the periodic table.
Ionization Energy is defined as the energy required to remove the atom of an electron.
Electron affinity is defined as the change in energy when electron is added to a negative ion.
Electronegativity is the ability of an atom to attract other atoms to itself.
