What metal is very chemicaly reactive?
Metals are highly reactive because of their characteristic electronic configuration, that is, the electrons in the atoms of metals have high tendency to leave their respective atoms and react with other species which have high tendency to accept electron.
What is a very reactive non metals?
The highly reactive non-metals are in the halogen group. They just need one more electron to fill the octet. Therefore they are highly reactive. For example fluorine and chlorine. And the highly reactive metals are placed in the first group (alkali metals). For example Sodium and potassium.
The first element with an electron in the second energy level?
Lithium
Which element does the first 7s electron appear?
Francium, Fr.
What makes element reactive?
Noble gases include Neon, Argon, Krypton, Xenon, Radon, Helium, and ununoctium.
Does magnesium have a greater first ionization energy than strontium?
About twice as large, which is not that much at the first ionization level. Still, Magnesium has a slightly larger, one proton nucleus and one more electron in that valence level to add to the energy needed to pill the first electron out of it's orbital. Electron shielding may have something to do with this also as the other valance electron of this 2+ element may shield the pulled electron.

What do all elements group 1 have in common in terms of electrons?
Group A1 of the Periodic Table (Hydrogen, Lithium, Sodium . . . ) is an Alkali Metal and only has one valance electron. If the element were to lose that electron, it forms an ion. Each element violently reacts when combined with water.
Why are the metals in the first group of the period table so reactive?
These metals lose easily an electron.
The first element with an electron in the second energy level?
Lithium
Which element does the first 7s electron appear?
Francium, Fr.

Noble gases include Neon, Argon, Krypton, Xenon, Radon, Helium, and ununoctium.
What is the symbol of the first element to have an electron in the 4d sublevel in its ground state?
The element is Yttrium, with the symbol Y
Should caesium element 55 be more or less reactive than potassium?
more reactive, the elements of the first column increase in reactivity as you go down
Which element contains the first p electron?
lithium
Where is the most reactive metal on the periodic table located?
This element is francium in the first group of periodic table.
