Answer:
The difference between the two is:
![[Kr]4d^1^05s^25p^2](https://tex.z-dn.net/?f=%5BKr%5D4d%5E1%5E05s%5E25p%5E2)
is the Orbital Occupancy
![[Kr]5s^24d^1^05p^2](https://tex.z-dn.net/?f=%5BKr%5D5s%5E24d%5E1%5E05p%5E2)
is the Orbital Filling Order
Both are correct, I don't think your teacher will be so nit-picky to care.
The answer is there is a one-to-one ratio of potassium ions to iodide ions.
Explanation :
- (K) belongs to Alkali metals in group (1A) that contains (1) electron in the outermost energy level, whereas, (I) is from halogens in group (7A) that contains (7) electron in the outermost energy level.
- To achieve stability, both atoms tend to reach the nearest noble state (outermost level occupies 8 electrons). Therefore, (K) loses its outer electron and gives it to (I) which now has a completely filled outer level and an ionic bond is formed between the two.
- The valency (number of electrons lost, gained or shared) of both atoms is equal ”monovalent” which means one-to-one ratio..
The top number of a portion is called its numerator whereas the bottom number is its denominator. So a Fraction is the quantity of shaded parts separated by the quantity of a balance of as demonstrated as follows: number of shaded parts is the numerator over the whole part which is the denominator.
Answer:
C
Explanation:
Neon is a noble gas, which is monoatomic.
