Hairstylists normally pay more as they are renting the chair/furniture and use hot water and much more electricity. Nail areas are typically just the space that you need.... nothing else. When you are a booth renter you have access to your space 24/7...
Germanium has 32 electrons per atom. 4 of those are valence electrons. Thus, germanium has 28 core electrons. Germanium has 32 electrons per atom. 4 of those are valence electrons.
On the third shell level (which is d) are 10 electrons. That leaves 3 electrons left at the 4th shell level. Those last 3 electrons are therefore the valence of Gallium (exactly like the valence of Aluminum, which is also 3). This means that Gallium, like Aluminum will be ready to lose 3 electrons and have a +3 charge, therefore it is a cation.
