Which noble gas doesn't have 8 outer electrons?
Helium has only 2 valence electrons. The rest noble gases have eight.
Do Aluminum has the greatest number of valence electrons?
No, aluminum does not have the greatest number of valence electrons. It has 3 valence electrons. Elements in column 18 of the periodic table (noble gases) have the maximum number of valence electrons, with helium having 2 valence electrons and radon having 8.
How many valence electrons do the nob gas element contain?
Noble gases have 8 valence electrons, except for helium which has 2 valence electrons. This full outer electron shell makes them stable and nonreactive under normal conditions.
What is odd element in the noble gases?
The odd element in the noble gases is helium because it has an atomic number of 2, while the other noble gases (neon, argon, krypton, xenon, and radon) have atomic numbers that are even.
How many valence electrons do noble gases have?
Inert gases have 8 valence electrons. This is why they are inert, they have a complete octet formed of electrons and are in their lowest energy configuration.
What is a element that has many valence electrons?
inert gases
Is the element reactive or satble how do you know?
If the element has a full valence shell, such as the noble gases, then it is unreactive. It the element is missing few valence electrons of has few valence electrons, then the element is very reactive, such as the sodium.
Elements in my family usually form covalent bonds. We have two fewer valence electrons than the noble gases. I am almost twice as heavy than the lightest element in my group. What element am i?
Sulfur: The periodic column containing elements with two fewer electrons than the noble gases is column 16, in which oxygen, the lightest element, has a mass number of 16. Sulfur, the next element in this column, has a mass number of 32.
Which group has different numbers of valence electrons?
Noble gases have a full valence shell with 8 electrons, while all other groups typically have fewer valence electrons. Transition metals have varying numbers of valence electrons depending on their position in the periodic table.

How many valence electrons do noble gases have?
Inert gases have 8 valence electrons. This is why they are inert, they have a complete octet formed of electrons and are in their lowest energy configuration.
Why does oxygen behaves only as a divalent element?
Oxygen typically exists as a divalent element because it has six valence electrons in its outer shell. By gaining two electrons, it can achieve a full valence shell, similar to the stable noble gases.
How valence electrons do noble gases have?
8, except for helium which has 2 valence electrons
What is odd element in noble gases?
The odd element in the noble gases is xenon (Xe). It has an odd number of protons and neutrons in its nucleus, unlike the other noble gases (helium, neon, argon, krypton, radon) which have an even number.
