Beryllium is a metal. It has 2 valance electrons (in the outer shell), and therefore it tends to lose those electrons in order to achieve a stable electron configuration, which in the case of beryllium is also 2 electrons, but in the inner shell. Nitrogen is a nonmetal, with 5 valence electrons, and it tends to acquire more electrons in order to reach a stable electron configuration of 8. Less energy is need to lose electrons when the result is going to be a stable electron configuration.
It needs just one electron to acquire a complete and stable outer shell.
false; it reacts so that they acquire the electron structure of a noble gas.
If an atom has three electrons, it will have one valence electron (valance = outer shell). It will be more likely to lose an electron than gain one, since it has only one to lose, but seven to gain.
Nonmetals will undergo chemical reactions that result in a stable electron configuration of 8 electrons in the outer shell. The number of valence electrons tells you have many they have in their outer shell prior to any chemical reaction, and therefore, how many more electrons they need to get a complete set of 8. So for example, oxygen has 6 valence electrons and therefore needs 2 more to have 8, so it will form an ion with a charge of minus two, which is the charge that is carried by the additional two electrons that oxygen will acquire. Chlorine has 7 valence electrons, therefore it needs just one more electron to complete its outer shell, and as an ion will have a charge of minus one. Nitrogen has 5 valence electrons, so it needs 3 more, and will form an ion with a charge of minus three.
helium, neon, argon, krypton, xenon, and radon.
Noble Gas
Sodium is an element which has one electron in its outer electron shell, and which can obtain a more stable electron configuration by getting rid of that electron. This causes it to undergo chemical reactions with other elements such as oxygen or chlorine, which need to acquire electrons in order to obtain a more stable electron configuration. If sodium reacts with water, it is reacting with the oxygen in the water molecule. In the case of sodium chloride, the sodium has already reacted with chlorine to form that compound, and has given up its outer electron, so it no longer needs to react with oxygen in water.
ionic crystal :) i finally found this answer... so happy!! i love answers.com!
when an electron is added to an atom, the atom will acquire a negative charge.

One can acquire configuration management training by attending workshops that specializes in this type, or going to meetings at one job company. They're usually free to attend.
For Mg to acquire the same electron configuration as Neon, it must lose 2 of its valence electrons. It thus obtains a 2+ charge. The 2 electrons that it loses can go to an accepting atom, such as O, S, Cl, etc. to form an ionic bond, where the accepting atom has a negative charge.
Atoms are reactive [except noble gases] because atoms have valence electron which try to acquire the stable configuration either by sharing, losing, or gaining of electrons. For e.g. Na is reactive as it consist of 1 electron in its valence shell which it can lose to combine with others..
They can do either - and they will. This is the fundamental mechanism behind the science we know as chemistry. Or Yes, they do. Some want to borrow some and some want to loan some out. This is the fundamental mechanism behind the science we know as chemistry.
Other elements can acquire a noble gas configuration by either gaining or losing electrons. Elements on the left side of the periodic table, such as alkali metals, tend to lose electrons to achieve a noble gas configuration. Elements on the right side of the periodic table, such as halogens, tend to gain electrons to achieve a noble gas configuration. Elements in the middle of the periodic table may gain or lose electrons to acquire a noble gas configuration, depending on the specific element and its properties.
It needs just one electron to acquire a complete and stable outer shell.
