Question

which number will give you an idea on the number of valence electrons?​

Answer 1

Answer:

The number that will give you an idea on the number of valence electrons is the Group number or the Family number. Let's say for example Group 1A, has 1 valence electron corresponding to the number of the group, Group 7A has 7 valence electron, Group 3B had 3 valence electron and so forth.

Answer 2

Answer: The Group number or Family number is the figure that will give you an estimate of how many valence electrons there are. Consider the following examples: Group 1A has 1 valence electron, Group 7A has 7, Group 3B has 3, and so on. Each of these groups has a matching number of valence electrons.

Explanation:

• The number of valence electrons for neutral atoms is the same as the number of the atom's main group. A periodic table element's column can be used to determine its main group number.
• Valence electrons, which are coupled to an atom and located in the outermost shell in chemistry, can take part in the creation of chemical bonds if the outer shell is not completely filled.
• The quantity of bonds that an element will form is known as its valence. This amount typically relates to how many electrons are needed to completely occupy the valence shell.
• A substance's valence is essentially determined by how many links its atoms have together.Valence electrons are those that are located in an atom's outermost shell.
• Understanding chemical bonds, such as the binding between hydrogen and oxygen atoms in the H₂O molecule, the bond between carbon atoms and oxygen in the CO₂ molecule, and many more, will be made easier with this knowledge.
