How many of each of the elementary particles are contained in the helium atom?
A helium atom consists of 2 protons, 2 electrons and 2 neutrons.
How many electrons does on atom of carbon contain?
In all there are 6 electrons, but the electrons are distributed over 2 shells. In the first shell, there are 2 electrons, and in the second there are 4 electrons. Note that this applies to the neutral atom of carbon.

How many protons and electrons does the element Helium have?
One atom of helium contains 2 protons and 2 electrons. The most abundant isotope of helium, helium-4, has 2 neutrons. The other, rare isotope of helium, helium-3, has 1 neutron. (Source: Wikipedia)
What atom contains 1 electron and 2 protons?
None, for it to be an atom it has the have the same number of electrons and protons. Something with 1 electron and 2 protons would theoretically be a helium ion but helium does not form ions.
What is the ionic charge of neutral calcium that contains 20 protons 20 neutrons and 20 electrons and loses two electrons?
A neutral calcium atom that loses two electrons has a +2 charge.
How many protons nuetrons and electrons does a helium at have?
A helium atom has 2 protons, 2 neutrons, and 2 electrons.
Does Mg 2 contains 15 protons and 10 electrons?
No, the element with an atomic number of 12 is magnesium (Mg), which contains 12 protons and 12 electrons in a neutral atom. If Mg 2 refers to a magnesium ion with a 2+ charge, it would have lost two electrons, resulting in 10 electrons.
What does an atom of 2 protons 2 neutrons and 2 electrons make?
If the atom has a balanced electrical charge, then # of protons = # of electrons, so the atom has 2 protons (Helium). The vast majority of Helium atoms have 2 neutrons.
Why is any atom neutral?
The atom has the same number of electrons as protons. electrons are negatively charged, and protons are positively charged. So for example in a Helium atom, it has 2 protons and 2 electrons, so the sub-particles cancel out, making the atom neutral.
