Option c is best.
Ok, thanks. (=
Yes, option C is correct. A metal from group 1 and a nonmetal from group 17 are likely to form an ionic bond.
To understand why this is the case, it is important to know a little bit about the properties of group 1 metals (also known as alkali metals) and group 17 nonmetals (also known as halogens).
Group 1 metals:
- Alkali metals are highly reactive metals located in group 1 of the periodic table.
- Alkali metals have a tendency to lose one electron to achieve a stable electron configuration.
- They have a low ionization energy, meaning it requires relatively little energy to remove an electron from their outermost shell.
Group 17 nonmetals:
- Halogens are highly reactive nonmetals located in group 17 of the periodic table.
- Halogens have a tendency to gain one electron to achieve a stable electron configuration.
- They have a high electron affinity, meaning they have a strong attraction for gaining an electron.
Based on these properties, when a metal from group 1 (such as sodium) reacts with a nonmetal from group 17 (such as chlorine), sodium loses one electron to form a positively charged sodium ion (Na+), while chlorine gains one electron to form a negatively charged chloride ion (Cl-).
The electrostatic attraction between the oppositely charged ions (Na+ and Cl-) leads to the formation of an ionic bond between the two elements. This bond is formed due to the strong attraction between the positive and negative charges of the ions.
Therefore, it is likely that a metal from group 1 and a nonmetal from group 17 will form an ionic bond.
