<u>Answer:</u> When an atom is an ion, it must have a charge.
<u>Explanation:</u>
An ion is formed when a neutral atom looses or gains electrons.
- When an atom looses electrons, it results in the formation of positive ion known as cation. <u>For Example:</u> Sodium looses 1 electron to form
ion. - When an atom gains electrons, it results in the formation of negative ion known as anion. <u>For Example:</u> Chlorine gains 1 electron to form
ion.
Hence, when an atom is an ion, it must have a charge.
Answer:
Same charge.
Explanation:
Ions in the same group tend to form ions with the same charge. Elements belong to the same group on the periodic table form ions with the same charge because they have the same number of valence electrons. For example, all members of alkali metals have different number of shells but same number of electrons in their outermost shell so due to same number of outermost shell these alkali metals will make bonding with halogens which is a seven group that have seven electrons and needs one electron for attaining stability and forming ions on both atoms.
The structure that corresponds to the molecule name - 4-heptanol would be option A.
<h3>Structure of 4-heptanol</h3>
The name, 4-heptanol, indicates that there are 7 carbon atoms in the structure.
In addition, there is also an indication that there is a functional group on the 4th carbon - the alcohol functional group.
Option B has only 6 carbon atoms instead of 7. Option A, on the other hand, fulfills all the criteria.
Thus, A is the correct structure of 4-heptanol.

It is an example of physical change. The molecules are not changing, so it is not chemical, and a physical property is something that a physical thing has.
