Generally metals lose electrons and nonmetals gain electrons.
Fluorine would be the more reactive element because it needs to gain one electron. While Barium needs to gain two electrons. Thus it is easier to gain one than to lose two.
Francium has the lowest electron affinity among all the elements because it is highly reactive and readily loses an electron to form a positive ion. This means that francium has a very low tendency to gain an electron.
When an atom loses an electron, it becomes positively charged and is called a cation. This loss of an electron reduces the number of negatively charged electrons compared to the number of positively charged protons in the nucleus. The atom becomes more reactive as it seeks to gain electrons to achieve a stable electron configuration.
Sodium, Potassium, and other alkali metals are very reactive due to the low ionization enthalpy. Flourine, Chlorine and other halogens are very reactive due to the high negative electron gain enthalpy.
an ionic compound is formed
Yes, fluorine is the most reactive element in the periodic table due to its high electronegativity and small atomic size, leading to strong attraction for electrons. Its reactivity stems from its tendency to readily gain an electron to achieve a stable octet electron configuration.
When we say valence electron we mean the number of electron left it the outermost shell of element, valence electron can be positive of negetive. If an element need much electrons to be octet, that means that the element is not reactive than the one who will give out electrons, the the one who can give electrons much are less reactive than the one who can give a litle and the reaction will be normal as it is soppused to be, Eg lithium and berylium. Lithium is more reactive than berylium because lithuin has 1valence electron while berylium has 2....reactivity goes with the action of valence electron in an element
Lithium loses one electron when it reacts
Calcium loses two electrons; the cation is Ca2+.
A reactive non metal is an element that can gain the electrons or is more electronegative
Oxygen can gain two electrons. Potassium form cation by loosing an electron. So they are reactive.
No, it becomes a new element.When a particle loses an electron it becomes an ion.
