What is the maximum number of valence electrons per atom?
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
Do metal atoms decrease in size when they combines with nonmetal atom?
As metals have to become metal ions in order to chemically combined with nonmetals they have to lose their valance electrons. This process is associated with making the atoms smaller.
How does the structure of a carbon atoms differ to other atoms?
A carbon atom has only four electrons in its valance energy shell. This allows for four other bonding possibilities. Carbon is also an atom that has covalent bonding properties which means it shares its electrons with the molecules that it is bonded to.

What does valance mean in science?
1. (biology) a relative capacity to unite or react or interact as with antigens or a biological substrate2. (chemistry) a property of atoms or radicals; their combining power given in terms of the number of hydrogen atoms (or the equivalent)
An electron that is found in the outermost shell of an atom and that determines the atoms chemical properties?
This electron is a valance electron.
How are valence electrons related to stability?
Valence electrons are the outermost electrons in an atom, and they determine the atom's chemical properties. Atoms with a full valence shell of electrons tend to be stable because they have a lower energy state. Atoms will gain, lose, or share electrons to achieve a full valence shell, which increases their stability.
Which electrons are the valance electrons of the atom?
Valence electrons are the electrons in the outermost energy level of an atom. These are the electrons involved in bonding with other atoms and determining the chemical properties of the element.

How can you find the valance electrons for an atom?
is a compound
How do you count lone pair in XeF4?
XeF4 Xe has 8 valance electrons. F has 7 valance electrons * 4 = 28 valance electrons 8 + 28 = 36 valance electron total. Now, there are 4 bonds between Xe and the 4 F's, so that is a total of 8 electrons shared. 36 - 8 = 28 valance electrons left over. That means that 6 each go around the fluorine atoms as three lone pair per atom and one electron for the exon atom, unless this is a charged molecule.
What does a valence shell have to do with chemical reactions?
The valance shell is important in chemical reactions, as it is the valance electrons which are gained/lost during reactions. An atoms valance electron configuration is what largely determines its chemical reactivity.
