Calculate the number of electrons , protons and neutrons in (I ) phosphorus atom (ii ) phosphate ion mass number=P=31,O=16 Atomic numbers:P=15,o=8 View Solution Calculate the number of neutrons present in the nucleus of an element X which is represented as3115X. ...
Is atomic mass the same as atomic number? How would you find the atomic number, atomic mass, protons, neutrons and electrons for ions and isotopes? How can you find protons, neutrons and electrons from an atomic number? How many elements have an atomic number of 42?
Carbon has an atomic number of 6. It states that there are 6 protons and 6 electrons in its atomic structure. We also know that carbon is an element whose number of protons is equal to the number of neutrons, which would be 6. Hence, the atomic mass is the sum of its protons and ...
One mole of water has a mass of 18 g, and each molecule of water contains 10 electrons. Determine the number of (a) electrons, (b) protons, and (c) neutrons in iron (2656 Fe). Calculate the net charge on a substance consisting of a combination of 4.3 multiplied by 1013 prot...
Calculate the mass number of an atom that is made up of 38 protons, 52 neutrons, and 38 electrons. The hydrogen atom contains 1 proton and 1 electron. The radius of the proton is approximately 1.0 fm (femtometer), and the radius of the hydrogen atom is ap...
electrons have so much less mass than protons and neutrons that they don't factor into the calculation. So, the atomic mass is the sum of the masses of protons and neutrons. There are three ways to find atomic mass, depending on your situation. Which one to use depends on whether you ...
Hydrogen has one proton, so it comes first, while oxygen has eight protons, so it's eighth. Atomic number is not the same as atomic mass, however, because you also have to add the mass of the neutrons in the nucleus. Electrons are so small and light that their weight is considered ...
Mass is a measure of "stuff," apart from whatever influence gravity has on that stuff. At root level, everything that has mass is made up of electrons, protons and neutrons (or if you want to be choosy, subatomic particles). One key property of mass is that gravity does act on it ...
We’ve just learned the simplest way to determine the weight of an atom of any particular element. Let’s perform the check using the weights of electrons, protons, and neutrons. This would not be so easy if gold had a number of isotopes. Gold has only one stable isotope however. What...
