Calculate the number of protons electrons and neutrons in helium-6?
Helium-6 has two protons and electrons and four neutrons.
Why does helium have an atomic number of 2 and atomic mass of 4?
An atom's atomic weight is the total of all protons and neutrons in its nucleus. Helium almost always contains two protons and two neutrons. Therefore, its atomic weight is 2 + 2 = 4.
What is the mass number of a helium atom that has 2 protons and 2 neutrons?
Number of neutrons = Mass number - Number of protons = 4 - 2 = 2 neutrons
List the number of protons electrons and neutrons has helium?
Helium has 2 protons and 2 electrons. He-3 and He-4 isotopes have 1 and 2 neutrons.
What is the superscript 4 for helium?
4He or He4. 4 stands for the mass number of Helium Mass number = number of protons + number of neutrons Since the atomic number or number of protons in helium is 2, the number of neutrons in He-4 is also 2.
What is the number of protons of helium?
Helium is number 2 on the Periodic Table, and the number of its mass is 4. So, therefore it has 2 protons, 2 neutrons, and 2 electrons !
What is the protons neutrons and electrons of helium?
The number of protons in an element is always the same as the atomic number, which is 2 in the case of helium. (The atomic number is assigned based on the number of protons in an element.) In a neutral atom (one with no charge), the number of electrons equals the number of protons, so it will be 2 electrons also. However, the number of neutrons will vary depending on the isotope (atoms of the same element with different numbers of neutrons). There are two stable isotopes of Helium, 3He and 4He, having 1 neutron and 2 neutrons respectively. Most helium is helium-4, and helium-3 is found as only about one atom in a million.See link below for more information on Helium, as well as the related question below that will show you how to find the number of protons, neutrons, and electrons in any atom.
What is the number of protons neutrons and electrons for Helium?
protrons=2 electrons=2 neutrons=2
How many number of protons in helium?
H2O has 10 protons. Hydrogen has 1 proton, so 2 hydrogen have 2 protons. Oxygen has 8 protons.
What is the number of protons neutrons and electrons does helium have?
1 Proton and 1 electron but no neutrons.
What does a number 4 indicate for helium?
4 is the mass number of helium (mass number = number of protons + number of neutrons)
What are the correct parts of an atom?
There are three parts to an atom. The nucleus consists of a proton or a combination protons and neutrons. The number of protons is the atomic number, and determines the element. For example, hydrogen has one proton. Helium has two protons and two neutrons. Varying numbers of neutrons represent different isotopes of that element. Deuterium is hydrogen with an additional neutron. The number of protons is generally matched by the number of electrons. If there is an imbalance, an ion (charged element or molecule) is the result. Electrons have a tiny fraction of the mass of either protons or neutrons.
