How many protons neutrons and electrons does the inert gas helium have?
2 protons, 2 electrons He-3 isotope has 1 neutron He-4 isotope has 2 neutrons
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.
What part of an atom is not involved in chemical reactions?
The nucleus of an atom is not involved in chemical reactions. The nucleus contains protons and neutrons, which do not participate in chemical bonding or reactions. Chemical reactions involve the electrons in the outer energy levels of an atom.
What makes element becomes active?
An element is chemically active till it does not attain an inert gas configuration.
Do inert elements gain electrons?
There is no electron exchange when no reaction takes place (this is what 'inert' means)

What is relationship of an atom with 12 protons 12 neutrons and 12 electrons to an atom with 12 protons 13 neutrons and 12 electrons?
Both those atoms are Magnesium but the second one is Magnesium25 not Magnesium 24 (standard Magnesium). Both have 12 protons and 12 electrons. Their charges are the same and their weights are the same.
What element has 3 protons 2 neutron and 2 electrons?
The type of a element is determined by the number of protons it carries. The element which have to protons is helium. An instance of the element with more electrons than protons, which makes it negatively charged, is called a anion or a negative ion. However, helium is one of, what are called, inert gases. The number of electrons in an inert gas is at the most stable number. It is quite hard to add or extract electrons from an inert gas. So without sounding absolute, He(-) is quite hard to come by.
How many protons nuetrons and electrons does neon have?
Every neon atom has 10 electrons. There are 10 and 12 neutrons in the neon-20 and neon-22 isotopes respectively.
How are helium and hydrogen different?
Hydrogen and helium, both gasses, differ greatly in:the number of protons and electrons (1 or 2),the number of neutrons (0 or 2),their Atomic Mass 1.0 or 4.0 ,and not at least in their reactivity (highly explosive or inert).
What element has 4 protons and 2 electrons?
Beryllium (Be) has 4 protons and 2 valence electrons.
How many electrons does argon have?
In its non-ionized state, which is usually how it is found since it's an inert gas, argon has 18 electrons.All atoms have the same number of electrons and protons. According to the periodic table, argon has 18 protons. It therefore also has 18 electrons.Number of Protons/Electrons: 18
What is the bohr diagram for helium?
The Bohr diagram for helium shows two electrons in the first energy level surrounding the nucleus, which has two protons and two neutrons. The electrons are positioned in a stable configuration with a full outer shell, making helium a chemically inert noble gas.
How are neon 22 and neon 20 alike?
A neon-20 atom has 10 protons and 10 neutrons within its nucleus, whereas neon-22 has 10 protons and 12 neutrons, making it an isotope.
