What is the number of protons neutrons and electrons in an atom of zirconium 90 that has overall charge and an atomic number of 40?

For an atom of Zirconium-90 with atomic number 40 and an overall charge of 0, it will have 40 protons and 40 electrons. Since the atomic number specifies the number of protons, and in a neutral atom the number of protons equals the number of electrons. As the charge is 0, the number of protons and electrons must balance each other out. The number of neutrons can be calculated by subtracting the atomic number from the atomic mass, so in this case, zirconium -90 indicates it has 50 neutrons (90 - 40).

What is -40 degrees Celsius in Fahrenheit?

Believe it or not ... -40°F.The two scales have equal numerical values at this temperature.Its the same, -40 degrees Celsius = -40 degrees Fahrenheit.Start by taking the number in Celsius and multiply it by 9.
