How many electrons must a neutral atom of helium posses?
helium has two electrons and has a charge of -2 for these electrons. However there are 2 protons in the nucleus and helium element as a whole is neutral.
How many protons neutrons and electrons are in helium?
Helium has two protons, since its atomic number is two. It is an inert element so it also has two electrons. The number of neutrons depends entirely on the isotope. The most common and stable isotope of Helium has 2 neutrons.
How many protons nuetrons and electrons does a helium at have?
2 protons, 2 electrons and 2 neutrons
How many protons and nuetrons are in helium?
The normal helium atom has two protons and two neutrons in the nucleus, and two electrons in the "shell".
How many protons and neutrons and electrons does helium-have?
Protons: 2 neutrons: 2 electrons: 2 Helium-3: 2 protons, 1 neutron, 2 electrons Helium-4: 2 protons, 2 neutrons, 2 electrons
How many atoms does the element helium have?
Helium IS an atom. It has 2 electrons and 2 protons making it a noble gas.
How many electrons must a neutral atom of helium posses?
helium has two electrons and has a charge of -2 for these electrons. However there are 2 protons in the nucleus and helium element as a whole is neutral.
How many electrons does helium have on the periodic table?
2. The atomic number which is 2 stands for how many protons (also electrons, in an uncharged atom) are in the element's atom.
How many protons and neutrons electrons in helium?
Helium has two protons, since its atomic number is two. It is an inert element so it also has two electrons. The number of neutrons depends entirely on the isotope. The most common and stable isotope of Helium has 2 neutrons.

How many elements in helium?
Helium is an element by itself with 2 protons
How many protons and neutrons and electrons does helium-have?
Protons: 2 neutrons: 2 electrons: 2 Helium-3: 2 protons, 1 neutron, 2 electrons Helium-4: 2 protons, 2 neutrons, 2 electrons
How many protons and electrons does a He have?
Helium has 2 protons and electrons and 1 or 2 neutrons, depending on the isotope.
How many electrons does helium?
Helium has two electrons. You can tell from looking at the periodic table because; each element has the same number of electrons as protons (the number of protons is the atomic number, which increases in number as you move from left to right across the periodic table, starting with one at Hydrogen).
