What is odd element in the noble gases?
Helium is odd as it has 2 valence electrons while others have 8 valence electrons.
What is odd element in noble gases?
The odd element in the noble gases is Radon. This is because it is radioactive, and all the others are highly unreactive.
How many valence electrons do the nob gas element contain?
noble gases all contain 8 valence electrons because they are in column 8A on the periodic chart
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?
Far from it. Aluminum has 3 valence electrons. The highest number is 8, which the noble gases other than helium have (helium has only 2). Metals can have 1, 2, or 3 valence electrons, so aluminum has the greatest number that an element can have if it is a metal. Once you get to 4 valence electrons (which the element carbon has) you are in the nonmetal range.
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.

Helium is odd as it has 2 valence electrons while others have 8 valence electrons.
What is odd element in noble gases?

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.

What are valence electrons and how do they relate to the noble gases?
Valence electrons are electrons in the outermost shell (or outermost energy level or outermost orbital) in an atom. Noble gases have 8 valence electrons. But helium (a noble gas) has only 2 valence electrons.
What do you notice about the number of electrons in each valence shell of noble gases?
All the noble gases have 8 electrons in their valence shell except helium which have 2 electrons in its valence shell.
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.
How valence electrons do noble gases have?
8, except for helium which has 2 valence electrons
