Answer:
An acid is a substance that releases H⁺ in aqueous solution.
Explanation:
There are different acid-base theories, such as Arrhenius, Bronsted-Lowry, Lewis, etc.
According to the Arrhenius theory, an acid is a substance that releases H⁺ in aqueous solution.
HCl(aq) → H⁺(aq) + Cl⁻(aq)
On the other hand, according to the Arrhenius theory, a base is a substance that releases OH⁻ in aqueous solution.
NaOH(aq) → Na⁺(aq) + OH⁻(aq)
A stable electron configuration has 8 valence electrons and a full octet, meaning that their would be a "happy" atom and it would be non reactive.
As a result, the protein molecule is 315 x 10^-9 metres long.
<h3>What does a hydrogen atom contain?</h3>
- The hydrogen atom is the most fundamental of all atoms because it just contains one proton and one electron.
- In addition to this most common isotope, the hydrogen atom can also be found in protium, deuterium, and tritium.
- Hydrogen, denoted by the letter H, has the first atomic number among the lightest elements.
<h3>How do you describe a hydrogen atom?</h3>
- There are three known hydrogen isotopes.
- Hydrogen has isotopes with masses of 1, 2, and 3, with mass 1 being the most common.
- This isotope is also referred to as protium and hydrogen in everyday language (symbol H, or 1H).

Answer:
76
Explanation:
Alpha decay is one of the most basic forms of radioactive decay. It has an atomic mass of 4 and a proton number of two.
Undergoing an alpha decay will decrease the atomic mass by four and the atomic number by two.
In this particular question, we are particular about the atomic number. The atom has an atomic number of 78. So taking 2 off this gives 76
