Answer: Family 16 is most likely to accept 2 electrons.
Explanation:
Family 16 has the electronic configuration 
. As to attain stability the p orbital will readily accept 2 electrons.
Therefore, family 16 is most likely to accept 2 electrons. Family 16 is also known as chalcogens.
Whereas, family 2 has the electronic configuration 
. As the s orbital is completely filled so there is no need to accept 2 electrons.
Family 12, and family 18 has the electronic configuration ![[Ar] nd^{10} ns^{2}](https://tex.z-dn.net/?f=%5BAr%5D%20nd%5E%7B10%7D%20ns%5E%7B2%7D)
and ![[He]ns^{2} np^{6}](https://tex.z-dn.net/?f=%5BHe%5Dns%5E%7B2%7D%20np%5E%7B6%7D)
respectively.
Both family 12 and 18 has completely filled orbitals so it will not accept any electrons.
Answer:
coevolution
Explanation:
Coevolution plays a key role in shaping the biodiversity on Earth. Coevolution is commonly defined as reciprocal evolutionary changes brought about by interactions between species, implying that interacting species impose selection on each other(Science direct).
We can see that the change that occurred in the plants of the tropical rainforests is closely related to their link to birds. The fruits evolved an attractive color so that birds, having evolved to eat the brightly-colored fruits, may eat them.
<span>The region(s) of the periodic table which are
made up of elements that can adopt both positive and negative oxidation numbers
are the “non-metal” region. As we can see on the periodic table, the elements situated
at the right side of the table have two oxidation states, one positive and the
other a negative. </span>
CO₂, will have the lowest boiling point among the following ,therefore option (d) is correct.
<h3>What do you mean by the boiling point?</h3>
The temperature at which liquid vapor pressure equals atmospheric pressure is referred to as boiling point.
The boiling point is defined as the temperature at which a liquid’s saturated vapor pressure equals the atmospheric pressure surrounding it.
The boiling point for any material is the temperature point at which the material transforms into its form.
The one with the lowest boiling point has the weakest intermolecular forces.
CO₂, will have the lowest boiling point among the following ,therefore option (d) is correct.
