How many sodium atoms are needed to provide electrons necessary to complete valence octet of oxygen atom?
2
Elements in the same group have similar properties because they have the same?
the same number of electrons needed to fill their octet, the same number of valence electrons,
How many electrons to most elements need to become stable?
Most elements need 8 electrons in their valence shells.
What are the electrons involved in the formation of a chemical bond called?
The valance electrons. The outer level of electrons every atom has. Every atom has a full valance shell at 8, so only the Nobel gasses are nonreactive naturally and other atoms either donate or accept the number of electrons needed to come to an octet of electrons.
What is the valance of electrons in carbon?
The atomic number of carbon is 6. 6 protons, 6 electrons. Two in the first shell and 4 on the second shell leaving 4 spaces open, making the second shell the valence shell and the 4 spaces open the valence- valence is the bonding capacity, in other words the electrons needed to fill the second shell. First shell max is 2 electrons Seccond shell max is 8 electrons
If calcium has two valence electrons and fluorine has seven how many fluorine atoms are needed to form an ionic bond with calcium?
two

How many valence electrons in fluorine are needed to have a filled outer energy level?
it has 2 because the first energy level has 1

How many valence electrons do each of the noble gases have. use this information to explian why the noble gases are unreactive?
A noble gas element has as many valence electrons as are needed to completely fill its valence shell: 2 for helium and 8 for all the others. Since a filled valence shell is the condition that other atoms are most likely to reach during chemical reaction, the noble gases are unreactive except with extremely electronegative elements such as fluorine, for which the chemical driving force for gaining an electron to fill the fluorine valence shell is stronger than the energy input required to extract an electron from one of the heavier noble gas atoms.
How many valence electron are needed for an atom to be stable?
It depends on the atom. List what element the atom is from.
What constitutes an electrons group?
lone pair of electrons & bonded pairs of electrons
How many electrons to most elements need to become stable?
Most elements need 8 electrons in their valence shells.

9,10
What is the number of valence electrons needed to make an atom stable?
8 - s2 and p6
