How are ionic charges used in creating chemical formulas for ionic compounds?

Chemistry

Answer:

Explanation:

Ionic compounds are formed by the positive and negative ions but over all compounds are neutral. Because total negative charges are equal to the positive charges and cancel the effect of each other.

For example:

sodium chloride is an ionic compound. It is made up of positive ion which Na⁺ and the negative ion which Cl⁻. The negative and positive charges are equal in magnitude thus cancel the effect of each other and make the compound over all neutral.

Na⁺Cl⁻ = NaCl

Another example:

Sodium carbonate: Na₂CO₃

This compound consist of cationic part which is Na⁺ and anionic part CO₃²⁻

In this compound carbonate have -2 charge while sodium have +1 charge . In order to balance the overall charges two sodium atoms are bonded with one carbonate unit. 2Na⁺ = +2 charge

thus,

Na₂²⁽⁺¹⁾CO₃²⁻ = Na₂CO₃

Materials that conduct heat and electricity well in the solid state result when: 1. metals bond with metals 2. any type of eleme
Andre45 [30]
Answer: Metals bond with metals.  
Explanation: A metallic bond is a sharing of electrons between many atoms of a metal element. Metallic bonding is when positive ions (metals) are in a 'sea of negative electrons'. The electrons are delocalised, which means they can move around easily and carry charge, and this enables it to conduct electricity, even in a solid state. The big pool of electrons is like a free-for-all in that any valence electron can move to any atom within the material.
