it is a noble gas, it doesn't do either one
Neither. It has a stable octet in its ground state.
Fluorine require only one electron to fill its outer shell. Hence it has the greatest tendency to gain electrons than Al, Rb and I.
Gold will lose electrons because it has two valence electrons in the S orbital
Increases on moving left to right
There are two reasons for that. Non metals do not have octet of electrons on their valence shell. Addition of electrons help them satisfy octet tule. Non metals have high electron affinity and hence high tendency to gain electrons.
No. Nonmetals generally gain electrons during chemical reactions.
Nonmetals gain electrons in chemical reactions.
metals have a tendency to lose electrons while nonmetals have a tendency to gain electrons. Metals are located left of the stair-step line and non-metals are located to its right.
You wouldn't expect strontium to gain electrons in a chemical change.
Yes, it is normal - in reduction reactions.
Neither. It has a stable octet in its ground state.
No. Nonmetals generally gain electrons during chemical reactions.
Fluorine require only one electron to fill its outer shell. Hence it has the greatest tendency to gain electrons than Al, Rb and I.
This is called a redox reaction, where one molecule gains electrons and one molecule loses electrons. Reduction is the gain of electrons and oxidation the gain of electrons. It can be remembered as OILRIG (Oxidation Is Loss Reduction Is Gain).
Gold will lose electrons because it has two valence electrons in the S orbital
Potassium would lose electrons in all its reactions especially with Bromine.
