1. The atomic number deceases by one and the atomic mass is unchanged - β⁺/positron emission. In this a proton is converted to a neutron, hence no net change in mass. Since a proton is converted to neutron, the daughter nuclide's proton number /atomic number decreases by 1. Then atomic number decreases by 1 and no change in mass.
2.the atomic number decreases by two, and the atomic mass decreases by four - alpha decay / ⁴₂α. alpha particles have 2 neutrons and 2 protons. Since 2 protons and 2 neutrons are emitted, the mass of the nuclide decreases by 4. Since 2 protons have been emitted, this results in atomic number decreasing by 2.
3.<span>the atomic number increases by one, and the atomic mass remains unchanged. - </span>β⁻ beta decay. In this type of decay - beta decay , a neutron is converted to a proton, therefore no net change in mass. Since a proton is formed, atomic number increases by 1. Therefore atomic number increases by 1 and no change in mass.
State the problem that you are trying to solve. Make sure that the hypothesis clearly defines the topic and the focus of the experiment.
Answer:
The answer to your question is
3KOH (aq) + FeCl₃(aq) ⇒ Fe(OH)₃ (s) + 3KCl (aq)
Explanation:
Data
Potassium hydroxide = KOH
Iron (III) chloride = FeCl₃
Iron (III) hydroxide = Fe(OH)₃
Potassium chloride = KCl
- Write the chemical equation
KOH (aq) + FeCl₃(aq) ⇒ Fe(OH)₃ (s) + KCl (aq)
Reactants Elements Products
1 K 1
1 Fe 1
3 Cl 1
1 H 3
1 O 3
This reaction is unbalanced
- Balancing the reaction
3KOH (aq) + FeCl₃(aq) ⇒ Fe(OH)₃ (s) + 3KCl (aq)
Reactants Elements Products
3 K 3
1 Fe 1
3 Cl 3
3 H 3
3 O 3
This reaction is now balanced
All phosphorus atoms have the same atomic number. Hope i helped

Hey, I will try my best
so as you know volcanos can be very destructive and cause mass death and deforestation. but nature needs volcanos because they are part of a cycle. The lava that comes from volcanos can feed various plants which will start to grow after an eruption. these plants will process the lava rock into food which feeds other plants. and soon enough you have a whole forest after all the lava rock has been processed.
