Best Answer. 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 ! Skylar Hagenes ∙. Lvl 13.
The number 2 in helium indicates the atomic number, which represents the number of protons in the nucleus of a helium atom. Helium has an atomic number of 2 because it has 2 protons.
The number 2 in helium indicates the atomic number, which represents the number of protons in the nucleus of a helium atom. Helium has an atomic number of 2 because it has 2 protons.
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 ...
Element number two is helium, and it has two protons, etc. What is the number of protons of hydrogen-1? Hydrogen will always have 1 proton regardless of the isotope. Trending Questions .
1 neutron. It has in its nucleus 1 neutron and 2 protons so its mass number is 3, hence whay it is called helium-3. (Mass number = # of protons + # of neutrons) because yo can't call it helium ...
A helium atom contains 2 protons, as well as 2 neutrons and electrons. Name: Helium; Symbol: He; Atomic number: 2 (read below what an atomic number is); Atomic weight: 4.002602; The atomic number ...
Understanding Helium-4 and Tungsten-184. Let's first explore helium-4. Helium-4 is a stable isotope of the element helium, represented by the symbol He. It has two protons and two neutrons, making its atomic mass 4. Isotopes of an element differ in the number of neutrons present but have the same number of protons.
How many number of neutrons in helium 3? 1 neutron It has in its nucleus 1 neutron and 2 protons so its mass number is 3, hence whay it is called helium-3. (Mass number = # of protons + # of neutrons)
The total number quarks in a helium nucleus which is composed of 2 protons (positively charged particle) and 2 neutrons (uncharged particle) is: Since there 3 quarks in each nucleon, 4 nucleons would have a total of 12 quarks. to work this out, just simply multiply 3 quarks to the number of nucleons:
