Answer:
The correct option is;
A) 1 to 1.
Explanation:
A stab;e nuclei requires the presence of a neutron to accommodate the the protons repulsion forces within the nucleus. An increase in the number of protons should be accompanied by an even more instantaneous increase in the number of neutrons to balance the forces in the nucleus. If there is an excess of neutrons or a deficit in protons a state of unbalance exists in the nucleus, which results to nuclear instability.
Therefore, the ratio of neutrons to protons is an appropriate way in foretelling nuclear stability and a stable nuclei is known to have a proton to neutron ratio of 1:1 and the number of protons and neutrons in the stable nuclei are usually even numbers.
Answer:
it states that the total mass of the products are the same as the total mass of the reactants in a chemical reaction.
Explanation:
An intensive property is a property that does not change depending on how much mass of it you are considered. An example of an intensive property is density. No matter how much water you examine, the density of the sample will be 1g/cm³.
Answer:
migratory distribution
Explanation: The pattern of migratory distribution of species may require collaboration between different countries for effective preservation. This is because species migration can make them enter different territories, which will need to provide an effective level of preservation for species survival

Answer:</h3>
D. Allotrope
<h3>
Explanation:</h3>
What is allotropy?
- Allotropy refers to the existence of an element in more than one physical forms.
- Allotropes are therefore different forms of an element with different physical properties or chemical arrangements.
What are some examples of allotropes?
- Examples of elements that exhibit allotropy include, sulfur and carbon.
- Allotropes of carbon are diamond and graphite.
- Allotropes of sulfur are monoclinic sulfur and rhombic sulfur.
