If you're looking for the balances equation to this the answer is
18 Ag + 3 Fe2(CO3)3 = 2 Fe3 + 9 Ag2CO3
Answer:
Covalent
Explanation:
In the carbon tetrachloride molecule, four chlorine atoms are positioned symmetrically as corners in a tetrahedral configuration joined to a central carbon atom by single covalent bonds
Based on the electronic configuration the elements are classified as metals, non metals and metalloids.
<u>Explanation:</u>
Periodic table consists of three major parts.
The left side consists of metals and the right side consists of non-metals and here Hydrogen element is the exception and in between those two regions we have metalloids, which has the dual character of both metals and non metals.
These elements can be grouped by means of its chemical properties and also due to its outermost electronic configuration.
If the valence shell electrons are same they are categorized under same group.
