What makes the elements in the halogen group reactive?
The halogen group elements are reactive because they have seven valence electrons, making them one electron short of a full outer shell. They are highly reactive and tend to gain an electron through reactions with other elements to achieve a stable electron configuration.
How many electrons must be gained or lost for calcium to attain a noble-gas electron configuration?
Calcium's electron configuration is [Ar] 4s2. To attain a noble gas configuration, calcium must lose 2 electrons to have the same electron configuration as argon, 4s2 3d10.
What is the different ways in which atoms try to attain the electronic configuration of noble gasses with an example?
Metals like sodium,potassium get noble gas configuration by losing electrons. Elements like nitrogen,oxygen get noble gas configuration by gaining electrons. Halogens get noble gas configuration by sharing electrons.
Does bromine tend to react by gaining electrons?
Yes, bromine tends to react by gaining electrons to achieve a stable electron configuration. It is a halogen and has seven valence electrons, so it typically gains one electron to complete its octet and attain a stable electronic configuration.
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.
Is the elecron configuration of an atom related to its tendency to give up or gain electrons during a chemical reaction?
Yes. If there are 1 to 3 valence electrons in an atom, then generally those elements will lose these electrons to attain noble gas configuration. If there are 5 to 7 valence electrons, then generally those elements will gain electrons to attain noble gas 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 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
How are elements form ions that have a stable atomic structure like that are found in a noble gases?
There are three different ways for this. Elements can either gain electrons or lose electrons or share electrons and attain a stable noble gas electronic configuration.
Why do elements participate in bonding?
Because in nature the elements seek to either give out electrons of take electrons. So the elements that gives out electrons bonds with the elements that takes electrons so that both of them are "happy"

How many electrons must a halogen gain to reach stability?
Halogens are in the seventh group on the periodic table, and thus have seven electrons in their outer shell. In order to attain a noble gas configuration, it must gain an electron to form an octet, which is when eight electrons are in the outer shell.
How do you get a noble gas configuration?
Atoms lose or gain or share electrons and tend to attain noble gas configuration
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.
