What else can I help you with?
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.
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
What is odd element in the noble gases?
Helium is odd as it has 2 valence electrons while others have 8 valence electrons.
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.
Which noble gas doesn't have 8 outer electrons?
Helium has only 2 valence electrons. The rest noble gases have eight.

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
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 many valance electrons does helium have?
Helium has two valence electrons. It is the only noble gas not to have eight valence electrons. Helium has the electronic configuration 1s2.The Noble gases have eight valence electrons in their outer shell.
