The given atom with 7 valence electrons is most likely to gain one more electron to achieve a full octet.
Given:
An atom with 7 valence electrons
To find:
Number electrons to achieve full octet by a given atom
Solution:
- The number of valence electrons in a given atom is 7.
- The number of valence electrons is 7 which means that the given atom will be a member of the halogen family.
- And as we know that halogen possesses one less electron to complete their octets. They by gaining one electron they achieve full octet and stability.
Similarly, the given atom with 7 valence electrons is most likely to gain one more electron to achieve a full octet.

Dry, white powder, soluble in water to form a slightly basic solution
Answer:
36% m/v
Explanation:
An antibiotic solution must be prepared by diluting 100. mL of a 90. % m/v solution and bringing up the volume to 250 mL. What is the concentration of the resulting solution?
the new solution is 100/250 X 90% m/v = 36% m/v
