SHELLS with definitive angular momentum
Answer
is: mass number stays 184, but atomic number changes.<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 (</span>atomic number Z is increased by one, new element is wolfram W) neutron is converted to a
proton and an electron and
an electron antineutrino.
In beta
plus decay (atomic number Z is decreased by one, new element is hafnium Hf), a proton is converted to a neutron and positron and an electron neutrino, so mass number does not change.

Explanation:
Stereoisomers are two or more atoms that have the same bonding order of atoms but there is a difference spatial arrangement of the atoms in space.
A plane of symmetry divides a molecule into two equal halves.
A chiral stereoisomer are not superimposed on a mirror image , Hence they do not posses a plane of symmetry.
As a result to that. these non-superimposable mirror images are said to be Enantiomers.
However, a Fischer Projection emanates from a two - dimensional figure which is used for presenting a three - dimensional organic molecules.
From the given question;
Fischer projection for an enantiomer of 2-bromo-2,3-dihydroxypropanal with the bromine oriented horizontally to the left and the hydroxide group oriented horizontally to the right.
we can sketch the way the enantiomer of 2-bromo-2,3-dihydroxypropanal can be seen like the one shown below:
CH₂OH

The objective of this question is to drawn the perspective formula of the molecule.
So , from the attached file below; we can see the perspective formula of the molecule in a well structured 3-D format.
The order of decreasing strength as oxidizing agent is Br₂ > Cu²⁺ > Fe³⁺.
<h3>What is Standard reduction potential?
</h3>
Standard reduction potential is defined as the reducing power of any element or compound
The standard reduction potential of Fe³⁺ is 0.77V.
The standard reduction potential of Br₂ is 1.09V.
The standard reduction potential of Cu²⁺ is 0.34V.
<h3>What is oxidizing agent?
</h3>
The species or compound which reduce itself and oxidize other species or compound by accepting electron is termed as oxidizing agent.
As we know that, with the increase in the standard reduction potential, the oxidizing power of particular species increases.
The increasing order of standard reduction potential is Cu²⁺ < Fe³⁺ < Br₂.
Thus, the decreasing strength as oxidizing agent is Br₂ > Cu²⁺ > Fe³⁺.

Answer:
A. Similar elements have such different masses that this would lead to a completely random arrangement of elements.
Explanation:
Because it is the number of protons, which is identical to the atomic number, that separates different elements from each other, not the atomic mass.
