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
The maximum number of valence electrons that an atom can have is 7, as seen in elements such as fluorine, chlorine, and bromine. These elements are in group 7A of the periodic table, also known as the halogens.
The maximum number of valence electrons an element can have is 8. This is because the outermost energy level, or valence shell, of an atom can hold a maximum of 8 electrons. Exceptions to this rule can occur for elements that can have more than 8 electrons in their valence shell through the process of expanded octet.
Valence electrons can be found in the s and p orbitals in an atom. The s orbital can hold a maximum of 2 electrons, while the p orbitals can hold a maximum of 6 electrons. This arrangement allows for a maximum of 8 valence electrons in an atom.
The valence is determined experimentally.
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.
Iodine has 7 valence electrons. I- contains 8 valence electron.

A calcium atom has two valence electrons.
The most valence electrons an atom can contain is eight.
A scandium atom has 3 valence electrons.
6 valence electrons
To find the number of non-valence electrons in an atom, you first need to determine the total number of electrons in the atom by looking at its atomic number on the periodic table. Next, subtract the number of valence electrons, which are the electrons in the outermost energy level of the atom, from the total number of electrons. The remaining electrons, which are not in the outermost energy level, are the non-valence electrons.
To determine the number of valence electrons in an atom based on its electron configuration, look at the outermost energy level of the atom. The number of electrons in this energy level is the number of valence electrons.
The number of valence electrons in an atom can be determined by looking at the group number of the element on the periodic table. The group number indicates the number of valence electrons an atom has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
Valence electrons can be found in the s and p orbitals in an atom. The s orbital can hold a maximum of 2 electrons, while the p orbitals can hold a maximum of 6 electrons. This arrangement allows for a maximum of 8 valence electrons in an atom.
