1) <span>this ion is an anion
cations are ions which have given out electrons and are positively charged
anions are ions which have taken in electrons and are negatively charged. the ion given has a negative charge which means it has taken in an electron therefore its an anion.
2)</span><span>what is the chemical symbol of the noble gas this ion is isoelectronic with ? atomic number of the ion is 10, this corresponds to the noble gas Neon - Ne.
</span>chemical symbol is Ne
3) <span>what is the formula of the ion?
the ion has a negative charge of -1. this means it has taken in one electron hence the electronic configuration before taking in the electron, when the </span>atom is neutral is 1s² 2s² 2p⁵
then the atomic number is 9, element with atomic number is fluorine.
therefore element is F
formula of ion is F⁻
Answer:
positive: proton
negative: electrons
no charge/nuetral: nuetron
Explanation:
no charge could be also described as nuetral.
I think it’s A but, don’t come at me if I’m wrong. Btw I read over it multiple times so this isn’t a random guess. Good luck tell me if you got it right
An atom is the smallest part of an element
When sodium phosphate reacts with sulfuric acid, forming sodium sulfate and phosphoric acid, the stoichiometric coefficient for sulfuric acid in the balanced chemical equation is 3.
In every balanced chemical equation, the total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side. The stoichiometric coefficient is the number written in front of each reactants and products that tells how many moles of each are needed in the reaction.
The chemical equation for the given reaction is:
+ 
= 
+ 
Put the necessary stoichiometric coefficient to balance each element.
Balancing Na:
+ = 
+
Balancing P:
+ = + 
Balancing S:
+ 
= +
Notice that H and O are already balanced.
Hence, the balanced chemical equation for the reaction is:
+ = +
where 3 is the stoichiometric coefficient of sulfuric acid, .
