Except for the noble gases, the atoms of all elements are unstable. This is why they form molecules and compounds, in order to become stable. Stable means having the same valence configuration as a noble gas. For all but the first two elements that means having an octet (8) of electrons in their valence shells after chemical bonding.
What else can I help you with?
Do elements tend to undergo chemical reactions that decrease stability?
Elements tend not to undergo chemical reactions that decrease stability. Chemical reactions typically result in products that are more stable than the reactants involved. Elements tend to form compounds to achieve a more stable electron configuration.
Why do elements need to attain a noble gas configuration?
All the elements in their normal state are reactive and unstable. In order to attain stability i.e. a state of minimum energy, they tend to form ions by loosing or gaining electrons. By doing so, they achieve stable electronic configuration or noble gas configuration. However, some elements do not form ions. Instead of that, two such atoms share electrons with each other and achieve this noble gas configuration. At the end, the main reason for attaining a noble gas configuration is to attain max. stability and min. energy.
How does electron configuration of ions derived from representative elements give them stability?
Ions derived from representative elements achieve stability by gaining or losing electrons to achieve a full outer electron shell. For example, Group 1 elements tend to form +1 ions by losing one electron to achieve a noble gas configuration, while Group 17 elements tend to form -1 ions by gaining one electron. This process allows the ions to attain a more stable electron configuration similar to that of a noble gas.
What does the band of stability for atomic nuclei refer to?
The band of stability is a way of viewing which isotopes of the elements are stable. If you make a graph of number of neutrons versus number of protons of the stable isotopes, you find that the stable isotopes make a thick curved line on the graph which is called the "band of stability." The lighter elements tend to have the number of neutrons equal to number of protons. The heavier elements tend to have more neutrons than protons. The band of stability can help you to predict the behavior of unstable radioactive isotopes as well, because you can predict which decay process will move the element closer to the "band of stability" so it will have the ideal ratio of neutrons to protons.
Why do elements chemically combine?
Elements chemically combine to form compounds in order to achieve a more stable or energetically favorable state. By sharing, gaining, or losing electrons, elements can attain a full outer electron shell and lower their overall energy. This results in the formation of chemical bonds and the creation of new substances with unique properties.
What does group 18 become when it is attain in the periodic table?
Group-18 belongs to inert elements. The elements attain stability.

How and why element combine?
elements combine to attain more stability, generally by attaining the electronic configuration of the nearest noble gases. they do so by donating electrons, accepting electrons or by sharing electrons
Why do elements react to form new substances?
Elements react to form new substances in order to achieve more stable electronic configurations. By forming bonds with other elements, they can attain a full outer shell of electrons, which is energetically favorable. This process allows elements to lower their overall energy and increase their stability.
What tends to gain electrons?
Elements on the right of the periodic table but not in group 0/8 tend to gain electrons. Those in group 7 tend to gain 1 electron and those in group 6 tend to gain 2.
What does the band of stability for atomic nuclei refer to?

Does elements of group 2 lend electrons?
Yes, elements of group 2 (alkaline earth metals) tend to lose 2 electrons to attain a stable electronic configuration, forming 2+ cations. This makes them more willing to donate electrons rather than accept them.
Did atoms attain stability after ionic bonding?
Atoms can achieve stability after ionic bonding by transferring or sharing electrons to attain a full outer electron shell. This process allows the atoms to reach a more stable electron configuration similar to that of noble gases.
Why do elements chemically combine?
Elements chemically combine to form compounds in order to achieve a more stable or energetically favorable state. By sharing, gaining, or losing electrons, elements can attain a full outer electron shell and lower their overall energy. This results in the formation of chemical bonds and the creation of new substances with unique properties.
What atoms can form an ion?
an atom which readily losses or gains electrons to attain stability forms an ion.
