All puppies are born blind and deaf. They are able to smell, and they use this sense to locate their mother even though they cannot see her. The milk in the mother's breasts has a scent the puppies are able to follow. Some puppies are born with cataracts, although these can improve with age. As the puppy grows, the lens grows as well, but the cloudy area that makes up the cataract does not increase in size. When the puppy reaches adulthood, the cloudy area is proportionally small compared to the rest of the lens.
K = #1s^2 2s^2 2p^6 3s^2 3p^6 4s^1#. This simplifies to a noble gas notation of:K = #[Ar] 4s^1#. Potassium (K) is an Alkali metal found in the first column (Group I) and in the fourth row (period 4) of the periodic table. All alkali metals end in #s^1# for their electron configuration. The total electron configuration for potassium is. K = #1s^2 2s^2 2p^6 3s^2 3p^6 4s^1#. This simplifies to a noble gas notation of. K = #[Ar] 4s^1#. We use the symbol for argon (Ar) because it is the last noble gas in the period (row) above potassium on the periodic table.
Question:I know that the electronic configuration of Cr only is [Ar] 3d5 4s1. But how about Cr2+? Answers:[Ar]3d4 4s0 elimination of electron starts from the outermost shell. Question:Write the electron configuration for the sodium atom and for the simple ion it most commonly forms. Indicate which noble gas has the same electron configuration as the ion. I've got about 20 more of these problems and I haven't a clue how to answer them. I'm hoping somebody can explain this to me so I can figure out the rest on my own.
