what happens to an atoms charge when it loses its electrons?
It becomes positive.
Why copper is deposited on iron nail when dipped in copper sulphate.?
It is an electrochemical reaction. Iron is more reactive than copper, meaning it is more easily loses electrons to form a compound. So the copper essentially "steals" electrons from the iron. Forming copper metal and iron sulfate.
Why do electrons only travel in one direction in voltaic cells?
The electrode potential or the reduction potential of zinc is less than that of copper. Therefore, zinc loses the electrons and copper ions gain them forming solid copper and producing electricity. Copper is not able to loose electrons due to presence of zinc and hence electrons flow in one direction only.
What happens to an element if it becomes a cation?
Cations are formed when elements lose electrons. Then they get positively charged.
What happens when an atom loses one or more electrons and retains the same number of protons?
This atom become a positive ion (cation).
Does copper gain or lose electrons?
it loses electrons
What happens when it loses electrons?
all elements want to have a full valence shell and when an atom loses electrons it is said to become a cation.
what happens to an atoms charge when it loses its electrons?
It becomes positive.
Why is zinc negative amd copper positive?
Zinc is more electronegative than copper. As a result, zinc acts as the anion(anode), while copper loses electrons and becomes positive (cathode). Electrons flow from the zinc to the copper ( - to +)
What happens to the charge of an atom that loses electrons?
it gets positive charge
What happens when magnesium forms it's ion?
it loses 2 electrons
What happens to metal in an ionic compound?
It becomes a cation - loses electrons
What happens when cations form?
an atom loses electrons and becomes positivly charged
What happens to sulfur atom when it becomes a sulphide ion?
It gains or loses electrons.
What do you think happens to the size of the electron when it loses and electron?
The ATOM decreases in size when it loses an electron and increases when electrons are added.
