Explanation:
proton normally = atomic number
protons = 9
Answer: Atomic mass of gallium = 69.72304093 amu
Explanation:
We calculate the atomic mass of Gallium by using the Relative abundance of the isotopes.
Atomic mass =mass x Natural Abundance of Isotope 1 +mass x Natural Abundance of Isotope 2
(60.11/100 x 68.9256) + (39.89/100 x 70.9247)
= 41.43117816 + 28.29186283 = 69.72304093 amu
In what meters? miles an hour? i can’t answer unless i know that
Means that the African continent was once in the higher latitudes, and in contact with Antarctica, where glaciers form due to the low temperatures in the poles. The continent drifted over time due to tectonic plate movement. Continental drift is powered by the convection current in the mantle of the earth.
