How many electrons protons and neutrons are found in the helium atom having atomic number 2 and mass number 4?
With the details you've given (which are correct) you can tell that because the atomic number is 2, He therefore has two protons. Because its Atomic Mass is 4 it therefore also has two neutrons (2 + 2 = 4)
What else can I help you with?
How do you figure the mass of an atom?
You add up the mass of the protons, neutrons, and electrons. Protons and Neutrons having an atomic mass of 1, and electrons having an atomic mass of roughly 1/1800.
Form of an element having different atomic and number of neutrons?
Isotopes have different numbers of electrons, but not different atomic numbers (numbers of protons) or they'd be different elements.
How many protons neutrons and electrons are in soduim?
Sodium's atomic number is 11. Thus, neutral sodium has 11 protons and 11 electrons per atom. 23Na is sodium's only stable isotope, having 23 - 11 = 12 neutrons.
How many neutrons and protons does a neutral atom of sodium with an atomic mass number of 23 have?
Every sodium atom has 11 protons, the atomic number of sodium. The isotope with mass number 23 has (23 - 11) or 12 neutrons, because the mass number of an isotope is defined as the sum of the numbers of protons and neutrons in the isotope.
How many protons and electrons and neutrons does berkelium have?
Number of neutrons = Atomic mass of an isotope - atomic number of the element The atomic number of berkelium is 97.Number of neutrons = Atomic mass of an isotope - atomic number of the element The atomic number of berkelium is 97.
How do you figure the mass of an atom?
You add up the mass of the protons, neutrons, and electrons. Protons and Neutrons having an atomic mass of 1, and electrons having an atomic mass of roughly 1/1800.
How many neutrons are there in an element having a mass number of 52 and an atomic number of 22?
30. The Atomic mass is essentially the protons + neutrons. The Atomic number is the protons. Or the neutrons. Or even the electrons. With the exception of ions and isotopes, those numbers are all the same.
What is the atomic number of a neutral atom having 6 electrons and 5 neutrons?
Atomic number is 6. The isotope is 6C11 Atomic number = number of protons = number of electrons (for a neutral atom)
How many protons neutrons and electrons are in xenon?
The protons and neutrons are packed together in the middle and the electrons have space to move, around them. logically their should be MORE neutrons and protons,but this depends on the size of the atom and how many atoms in the neon. info from SUSSEX UNIVERSITY.
How many electrons neutrons and protons are found on the helium atom having atomic number 2 and mass number 4?
The atomic number is 2. So there are 2 protons and 2 neutrons. For a mass number of 4, there will be 2 neutrons (4 - 2 = 2)
How do you calculate the atomic mass of an element?
If you know the mass of one mole of those atoms (the mass number listed on the periodic table), then you divide that number by Avogadro's constant: 6.022x10^23 which gives you the mass of one single atom
Which element has 5 protons 7 neutrons 5 electrons and a mass of 12?
The element with 5 protons and 7 neutrons would be Boron (atomic number 5). However, the element also having 5 electrons doesn't match the standard atomic structure, so it could be an ionized form of Boron.
Form of an element having different atomic and number of neutrons?
Isotopes have different numbers of electrons, but not different atomic numbers (numbers of protons) or they'd be different elements.
How many protons neutrons and electrons are in soduim?
Sodium's atomic number is 11. Thus, neutral sodium has 11 protons and 11 electrons per atom. 23Na is sodium's only stable isotope, having 23 - 11 = 12 neutrons.
How many neutrons and protons does a neutral atom of sodium with an atomic mass number of 23 have?
Every sodium atom has 11 protons, the atomic number of sodium. The isotope with mass number 23 has (23 - 11) or 12 neutrons, because the mass number of an isotope is defined as the sum of the numbers of protons and neutrons in the isotope.
Number of protons neutrons and electrons in zinc?
When it comes to zinc, the amount of neutrons is considerably higher than the number of protons and electrons. In zinc there are 30 protons include, 35 neutrons and 30 electrons. Unless you are dealing with Ion, the number of protons is always equal to the number of electrons.
What is the electron number of zinc?
30 electrons. Zinc-66 stands for Zinc having 66 as the Atomic Mass. We know Zinc has 30 protons and we can assume that it's in a stable state so there would be 30 electrons. This means there's 36 neutrons. (30[protons] + 36[neutrons] = 66[atomic mass]
