The correct balanced equation of a beta decay undergone by Mercury-203 is as follows:
203 80 Hg → 203 81 + 0 -1 e
<h3>What is beta decay?</h3>
Beta decay in radioactivity refers to the release of a beta particle by a radioactive element.
Beta particle is characterized by the possession of mass number 0 and atomic number -1.
This means that if Mercury-203 undergoes beta decay, the atomic number of the resulting isotope will be +1 as follows:
203 80 Hg → 203 81 Tl + 0 -1 e

Answer:
From gas laws (pressure law and Boyles law), the pressure exerted by a gas depends on Temperature of the gas and volume of the container.
Explanation:
• P → Pressure exerted by the gas.
• T → Temperature of the gas.
• V → Volume of the container.
• from the expression, pressure exerted by the gas is directly proportional to temperature of the gas and inversely proportional to the volume of the container.
The variable X is the effective nuclear charge, and it remains constant down a group.
Discussion:
The effective nuclear charge is referred to as the actual amount of positive (nuclear) charge experienced by an electron in a polyelectronic atom.
The effective nuclear charge experienced by an electron is otherwise called the core charge.
It is mathematically evaluated as the difference in the atomic number and the core electrons. and since elements in the same group have equal number of Valence electrons, the effective nuclear charge is constant down the group.
