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. Then divide that number by 5, and then add 32. This is how you convert Celsius to Fahrenheit or use the equation F = (9/5)C + 32In this case, the answer is also -40 degrees Fahrenheit.(-40) degrees Celsius = (-40) degrees Fahrenheit-40 degrees Celsius = -40 degrees FahrenheitAnswer: -40 ºC = -40 ºF-40
What is -40 Centigrade equal in Fahrenheit?

What do the superscript and subscript mean in the notation 40 K represent 19?
The superscript (40) represents the mass number, which is the total number of protons and neutrons in the nucleus of the atom. The subscript (19) represents the atomic number, which is the number of protons in the nucleus of the atom. Therefore, in the notation 40 K represent 19, the atom is potassium with a mass number of 40 and an atomic number of 19.

48 is 40 percent of what number?
To find the number that 48 is 40% of, you can set up a proportion. Let x represent the unknown number. The proportion would be: 48/x = 40/100. Cross multiplying, you get 48 * 100 = 40x. Simplifying this equation gives you 4800 = 40x. Dividing both sides by 40, you find that x = 120. Therefore, 48 is 40% of 120.
