Why metals react by losing electrons whereas halogens react by gaining electron?

Metals have a few electrons fairly loosely bound in their outer "shells", while halogens have nearly-complete outer electron "shells". The most stable configuration for an atom is to have completely-filled shells, so it's easy for metals to lose an electron or two and get down to the next "completely filled" shell, while halogens pick up extra electrons to get to the next filled shell.

Is true or false electron and neutron have opposite charge?
False, electrons are negatively charged whereas neutrons have no charge. An electron is of opposite charge to a proton which has a positive charge.
Which atom has a lower ionization energy aluminium or boron?
The maximum capacity of electron accommodation in aluminium is 18 electrons( M shell) on contraty it has only 3 valence electrons whereas boron has maximum capacity of 8 electrons(L shell) and it has 3 valence electrons so electron population of Aluminium is less than that of boron.
How many energy levels would electrons of hydrogen and helium fill?
1st energy levels only in which hydrogen will have only one electron whereas helium will have two electrons.
What does it it mean to say that some elements are reactive and form ions easily whereas others do not?
Elements form ions by either gaining or losing valence electrons. The elements that lose electron(s) and gain electron(s) acquire a positive charge and negative charge respectively. The elements that lose and gain the least electrons require less ionization energy, and are more reactive than elements that need to lose or gain more electrons. For instance, elements in group 1 of the Periodic Table need to lose one electron, and are more reactive than elements in group 2 that need to lose 2 electrons.
How do the alkali metals differ from the alkaline earth metals?
alkali metals have one valence electron, whereas alkaline earth metals have two valence electrons.
Why do elements in th alkali metals group often form iconic bonds with the halogen group?
Alkali metals have one electron in their valency shell whereas halogens have seven. By losing al electron to a halogen, both ions get a full set of electrons in their valency shell.
How many valence electrons do atoms in period 1 have?
Hydrogen has 1 valence electron, whereas helium has 2 valence electrons.
Why is there a large increase in ionic radius from silicon to phosphorus?
Because while silicon loses electrons to be stable, it loses an electron shell, whereas phosphorus gains more electrons. Therefore, there is a difference of an entire electron shell.

What group of elements do not have an identical outer electron configuration?
noble gases Helium has 2 valence electrons, whereas the rest have 8.
Is Halogen a metals?
no halogens are not metals as they are on the left side of the Periodic Table which appears to be the side of non metals they have tendency to gain electron where as metals have tendency to donate or give electron they form covalent bonds whereas metals form ionic bonds these are few differences hope you find more :) Too bad halogens are on the RIGHT side, which is where nonmetals are. Left side is metals. Ding dong. ^^GREAT ANSWER (FROM ANOTHER PERSON) :)
Why Oxygen is react more slowly than halogens?
Oxygen does not react more slowly than all of the halogens, just some of them. Plus, the rate of a reaction depends on its nature, not just whether oxygen or a halogen reacts. when the halogens do react faster, this is because they only need one electron to have a stable configuration, whereas oxygen needs two.

Copper metal conducts electricity through electrons whereas it solved solution conducts electricity through ions do you agree?
no,if it is dissolved in solutions it conducts electricity through electron the electricity means flow of electrons.
