beta-plus decay
Explanation:
This is a nuclear reaction. In chemical reactions, atomic number does not change.
A beta plus decay is a decay that decreases the atomic number by 1 and leaves the mass number unchanged.
For example, let us us a hypothetical decay of Oxygen-16 by beta plus decay:
¹⁶₈O → ¹⁶₇N + ⁰₁Β
⁰₁Β this is a beta plus particle
The mass number of oxygen in going to Nitrogen is sustained but the atomic number is reduced by 1. The emission of a beta plus particle will produce this kind of effect.

Answer is: the amu of a sodium atom is 23.
The unified atomic mass unit (amu) is a standard unit of atom mass.
One unified atomic mass unit is approximately the mass of one nucleon (proton or neutron).
The unified atomic mass unit is equal 1.66·10⁻²⁷ kg.
n(p⁺) = 11; number of protons in sodium atom.
n(n°) = 12; number of neutrons of sodium atom.
n(p⁺ + n°) = 11 + 12.
n(p⁺ + n°) = 23; number of nucleons in sodium atom.
Answer:
START and STOP, ReAcTanTS means START, PrOducTS means STOP
Explanation:
1. We find words 'STOP' and 'START'.
2. Let's take a look at the word 'ReAcTanTS'. Enumerate the capital letters from 1 to 5 from left to right, that is,
'1': R,
'2': A,
'3': T,
'4': T,
'5': S.
Notice that if we take a combination of 54213, we obtain a word 'start'. This has, of course, a chemical application. Reactants are the ones we start with in a chemical reaction.
3. Let's take a look at the word 'PrOducTS'. Enumerate the capital letters from 1 to 4 from left to right, that is:
'1': P,
'2': O,
'3': T,
'4': S.
Notice that if we take a combination of 4321, we obtain a word 'stop'. Similarly to the previous word, it also has a direct relationship to the chemical context. Products are formed in a chemical reaction when reactants combine. This is the point where reaction comes to and end and eventually stops if it's a typical one-sided reaction.
Yes, it is the power of material evidence that wins.
- Evidence used to support or refute a scientific theory or hypothesis is known as material evidence.
- Evidence is also used by scientists in various contexts, such as when they apply ideas to real-world issues.
- Whether a person accepts the data as proof depends on their presumptions or views regarding how observations relate to a theory.
- A creative hypothesis is developed by a scientist and may be refuted by testing it against evidence or established truths.
- Evidence can refute a hypothesis by demonstrating facts that are at odds with it. In contrast, the presence of evidence does not preclude the possibility of future, undiscovered evidence supporting the idea.
Therefore, it is the power of material evidence that wins, not the authority of experts that
proves an answer in Science.
