What else can I help you with?
Which is more reactive fluorine or barium and why?
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.
What is the electron affinity of francium?
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.
What happens when a atom loses 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.
What element are most reactive on the table?
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.
What is it when 2 atoms gain or loses an electron?
an ionic compound is formed
Is fluorine the most reactive element?
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.
What is the relationship between an element's number of valence electrons and its reactivity?
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
How many electrons does lithium gain?
Lithium loses one electron when it reacts
Does calcium gain electron?
Calcium loses two electrons; the cation is Ca2+.
What is an reactive nonmetal?
A reactive non metal is an element that can gain the electrons or is more electronegative
Why are oxygen and potassium reactive?
Oxygen can gain two electrons. Potassium form cation by loosing an electron. So they are reactive.
Does an ion of an element lose or gain protons to become a charged particle?
No, it becomes a new element.When a particle loses an electron it becomes an ion.
