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.
Ions form when an atom releases its electron or gains it, to or from another atom. For example, Na. The atomic number of Na is 11, which means, the electron configuration of Na will be. 1s2 2s2 2p6 3s1. Na has one electron valence. Na tends to release that last electron to form the cation (positive charged ion), which is Na+
