Question

Can you name the anion and cation present in $MgC{l_2}$ .

Answer 1

Hint : Because magnesium's electrical configuration is [2,8,2], it has a valency of 2 +. Magnesium's closest noble gas is neon, which has an electronic configuration of [2,8]. In order to obtain this stable electronic configuration, Mg must shed two valence electrons, resulting in a valency of 2+.

Complete Step By Step Answer:
Ions are a type of ion that is studied in science. Chemistry is made up of atoms and electrons that have gained or lost weight as a result of the removal or addition of one or more valence electrons, resulting in a positive or negative charge. Negatively charged ions are known as anions, whereas positively charged ions are known as cations. Because both of them have charges with opposing characteristics, they are attracted to one another and create an ionic connection.
Cations are ions with a positive charge. When a metal loses its electrons, they form. They lose one or more electrons but none of their protons. As a result, they have a net positive charge. Calcium ( $C{a^{2 + }}$ ), potassium ( ${K^ + }$ ), and hydrogen ( ${H^ + }$ ) are examples of cations.
Anions are ions with a negative charge. When a non-metal obtains electrons, they form. They receive one or more electrons while retaining all of their protons. As a result, they have a net negative charge. Iodide ( ${I^ - }$ ), chlorine ($C{l^ - }$), and hydroxide ( $O{H^ - }$ ) are examples of anions.
In $MgC{l_2}$ , the anion present is $M{g^{2 + }}$ and the cation present is $C{l^ - }$ .

Note :
The number of electrons present in an atom's outermost shell, also known as the valence shell, is referred to as valency. These electrons are crucial to study since they are the atoms' most loosely held electrons.
Magnesium is an atomic number 12 element. It's just after the sodium nitrate. Magnesium is found in group 2A of the periodic table, according to the periodic table.
