For the First part I believe elements naturally exist in nature and compounds are formed so elements can be more stable. (I think this is right I’m not 100% but I’m close)
For the second part the two main types of bonds are ionic and covalent. Ionic bonds involve the transfer of electrons and covalent bonds involve the sharing of electrons. (I’m 100% on this one)
Answer:
On the placement of hydrogen and helium in the periodic system
H1=1
He2=2
Answer: Yes , in , two electrons from magnesium are transferred to chlorine atoms.
Explanation:
Ionic compound is formed by the transfer of electrons. For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
For example : For formation of
Electronic configuration of magnesium:
Magnesium atom will loose two electrons to gain noble gas configuration and form magnesium cation with +2 charge.
Electronic configuration of chlorine:
Chlorine atom will gain one electron to gain noble gas configuration and form chloride ion with -1 charge.
In Magnesium chloride two electrons from magnesium metal gets transferred to two chlorine atoms and thus is formed.
