There can be up to 18 valence electrons in a atom, these atoms are krypton, xenon, radon, and sometimes mentioned is ununoctium but is an "unknown element" so the element is not always mentioned

What is the maximum number of valence electrons that an atom can have excluding hydrogen helium and beryllium?
The maximum number of valence electrons will vary from element to element ranging from 1 to 8.
What is the maximum number of electrons th eouter most valence energy level can hold?
The maximum number of electrons that any atom can hold in its outer valence is 8. Oxygen has the electron configuration of 1s2 2s2 2p4, which means it can accept two more electrons.
How can you determine the number of valence electrons an atom has?
The valence is determined experimentally.
How can you determine the number of valence electrons in an atom?
You can determine how many valence electrons an atom has by what family the element of the atom is in. For instance, if the element is in family 8A, the number of valence electrons will be 8. Or, if the element is in family 2A, the number of valence electrons for the atom will be 2. So, whatever number family the atom is in, the number of valence electrons equals that.
What is beryllium number of valence electrons?
The beryllium atom has 4 electrons and the valence is 2.
What is the maximum number of valence electrons that an atom can have excluding hydrogen helium and beryllium?
The maximum number of valence electrons will vary from element to element ranging from 1 to 8.
What is the maximum number of electrons in the l- orbit of an atom?
Iodine has 7 valence electrons. I- contains 8 valence electron.
Each energy level of an atom has a maximum number called?
valence electrons
State the number of valence electrons in an atom of calcium?
A calcium atom has two valence electrons.
What is the highest number of valence electrons an atom can have?
The most valence electrons an atom can contain is eight.
Number of valence electrons in an atom of sulfur?
6 valence electrons
The number of valence electrons in gallium?
There are 3 valence electrons in a gallium atom.
How do you figure out the core charge of an atom?
the atomic core charge of an atom is the same as the number of valence electrons in the atom
What do the electrons in an electron dot structure represent?
It represents the number of valence electrons in the atom.
The chemical properties of an atom depend on the number of what?
It depends on the number of electrons in the outer valence shell in the atom
What is the maximum number of electrons th eouter most valence energy level can hold?
The maximum number of electrons that any atom can hold in its outer valence is 8. Oxygen has the electron configuration of 1s2 2s2 2p4, which means it can accept two more electrons.
