How many electron must phosphorus gain in order to achieve an octet?
This atom must gain 3 electrons to achieve an octet.
When two nitrogen atoms combine to form a nitrogen molecule how many electrons are shared to give each atom a complete octet?
One atom of nitrogen has 7 protons, 7 neutrons, and 7 electrons.
Is water an exception to the octet rule?
It is one of many, many exceptions to the octet rule. Hydrogen does NOT require 8 electrons.
How many electrons are required to reach an octet in Be?
An octet is 8 electrons- but even 2 electrons are okay for achieving stability. A beryllium atom has 2 shells, with 2 electrons in each shell. Since it is a metal, it will lose electrons instead of gaining them, forming a positively charged ion. This means that it will lose both the electrons in its outermost shell, leaving it with a single shell containing 2 electrons. So, basically beryllium loses 2 to electrons to form a stable duet with a charge of 2+! Hope this helped you (:
Explain how to use the valence electrons in an atom to predict if the atom will form bonds.?
An atom wants to have a full octet and thus the number of valence electrons is the key to finding how many bonds should be formed to complete this octet.For example: H2OOxygen has 6 valence electrons. To achieve a full octet (i.e. eight valence electrons on the outermost shell), it needs two more electrons. Hydrogen has 1 electron available for bonding, thus two hydrogen atoms would provide oxygen with the two electrons it needs. Thus the compound, H2O is formed.Another example is CO2Carbon has 4 valence electrons. Oxygen has 6. Each wants a full octet. Thus, carbon shares two of its valence electrons with each oxygen. In the end, Carbon has its original 4, plus two from each oxygen atom, which totals to eight. Oxygen has 6 originally plus 2 shared electrons from carbon thus a full octet is achieved.
How many electrons must a chlorine atom gain to complete its octet?
One.
How many electrons do a octet bromine have?
Bromine is a non metal element. There are 35 electrons in a single atom.
How many electrons does a potassium atom need to donate to another atom to satisfy the octet rule?
It depends which 'other atom' it is
How many electron must phosphorus gain in order to achieve an octet?
This atom must gain 3 electrons to achieve an octet.
How many electrons that an atom in the oxygen family gain or share?
Atoms in the oxygen family can gain or share two electrons in order to achieve an octet of electrons.
How many sodium atoms are needed to provide electrons necessary to complete valence octet of oxygen atom?
2
How many electrons would an atom of magnesium have to lose to have a stable octe?
It'll have to lose two to have a stable octet.
How many electrons are in the Na ion?
When sodium becomes an ion, it loses one electron to fulfill the octet rule. A neutral sodium ion has 11 electrons, so an ion will have 10.
How many electrons will each atom either gain or lose in order to satisfy the octet rule of Na?
Sodium would LOSE 1 electron to satisfy the octet rule.
How many protons and electrons are in the nucleus of a chlorine atom?
A single chlorine atom has 17p+ (Protons) and 17e- (Electrons). Chlorine will form a 171- anion by gaining one electron, completing the valence shell as an octet.
When two nitrogen atoms combine to form a nitrogen molecule how many electrons are shared to give each atom a complete octet?
One atom of nitrogen has 7 protons, 7 neutrons, and 7 electrons.
How many electrons are called are needed in the outer energy level of most atoms for the atom to be stable?
Eight electrons, called an octet, are needed by most atoms in order to be stable.
