Answer:
SA node (sinoatrial node)
So I will match them but by words so if necessary you will have to do the number letter pairing.. kool:
protons plus neutron = atomic mass
proton number = atomic number
detects radiation = Geiger Counter
fixed shape = solid
neutral charge = neutron
positive charge = proton
occupies the whole container = gas
measures the intensity of radiation = photographic film
smallest particle to retain characteristics = atom
negative charge = electron
Hope this helps and doesn't leave you with too much work
Phosphorus has an electronic configuration in the simple form 2,8,5 and a spdf configuration of 1s² 2s² 2p⁶ 3s² 3p³.
The valence electrons in phosphorus (the electrons available for bonding) are 5. As a result, an atom of phosphorus shares its electrons with another atom to form COVALENT bonds. This is ideal since it would take a high amount of energy to release these five electrons, and it would be unlikely for atoms to lose 5 electrons to donate to phosphorus.
D. Growth. Material forming cells or tissue like cytoplasm.
