Magnesium has 12 protons. What charge do you expect it to have when it ionizes? Why?

olya-2409 [2.1K]

Answer: This element has +2 charge on it.

Explanation:

An ion is formed when an atom looses or gains electrons.

When an atom looses electrons, it leads to the formation of positive ion known as cation.
When an atom gains electrons, it leads to the formation of negative ion known as anion.

Magnesium is the 12th element of the periodic table having electronic configuration of $1s^22s^22p^63s^2$

This element will loose 2 electrons to attain stable electronic configuration and leads to the formation of a cation having formula $Mg^{2+}$

Hence, this element has +2 charge on it.

The reaction, 2C4H10 (g) + 13O2 (g) à 8CO2 (g) + 5H2O (g), is the combustion of butane. What occurs as the reaction proceeds?

Solnce55 [7]

The reaction, 2 C4H10 (g) + 13 O2 (g) = 8 CO2 (g) + 5 H2O (g), is the combustion of butane. A combustion reaction involves the reaction of a hydrocarbon with oxygen producing carbon dioxide and water. This reaction is exothermic which means it releases energy in the form of heat. Therefore, as the reaction proceeds,a heat energy is being given off by the reaction. This happens because the total kinetic energy of the reactants is greater than the total kinetic energy of the products. So, the excess energy should be given off somewhere which in this case is released as heat.
