Which elements are the most reactive and why?

worty [1.4K]

Answer:

Fluorine is identified as the most reactive nonmetal and the most electro-negative element in the periodic table, making it the strongest oxidizing agent. Caesium is the most reactive metal in the periodic table, so much that working with this metal often ends in explosions!

Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.

Hope that helps.

the first three ionization energies of an element x are 590, 1145, and 4912 kj mol-1. what is the most likely formula of the com

joja [24]

<u>Answer:</u> The chemical formula is $XSO_3$

<u>Explanation:</u>

Ionization energy is defined as the amount of energy that is required to remove an electron from a chemical species.

The ionization energy equation for the given values follow:

$X(g)\rightarrow X^+(g)+e^-;E_I=590kJ/mol$

$X^+(g)\rightarrow X^{2+}(g)+e^-;E_I=1145kJ/mol$

$X^{2+}(g)\rightarrow X^{3+}(g)+e^-;E_I=4912kJ/mol$

From the values of ionization energy above, it can be seen that the ionization energy increases as every succeeding electron is removed.

Second ionization energy is a little higher than the first one but there is a huge amount of difference between the third and second ionization energy.

This implies that the ion formed during second ionization energy has a stable configuration and it requires a humongous amount of heat to release the third electron.

Hence, the ion formed will be $X^{2+}$
