Be patient and do not disturb the puppy or the mother unless absolutely necessary. Mother dogs and puppies need time to bond while the puppy continues to develop. Most puppy's eyes and ears open within 10 to 18 days. Check the puppy around 10 days of age. The eyes and ears may not be open yet, but you will probably be able to see some signs of development. You should be able to see the formation of the ear canal at this age, although the ears themselves will not be open.
Helium has 2 electrons. hydrogen has one electron. Hydride ion is formed when hydrogen gains one electron, and thus hydride ion will also have 2 electrons.
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.
