<span>The choices for this question can be found elsewhere and as follows:
Silver is a transition metal with electrons in the d shell.
Silver atoms have 47 protons in their nuclei.
Silver atoms commonly form ions with a +1 charge.
I think the correct answer is the last option. The least reliable information would be that s</span>ilver atoms commonly form ions with a +1 charge.
Answer:
to determine of it is a solid liquid or gas.
Explanation:
The melting point is the temperature at which a substance converts from a solid state to a liquid state.
First, the symbol for sodium oxide is Na₂O
Each Na (sodium) has a charge of 1+, and each O has a charge of 2- :
Na₂¹⁺O²⁻
There are two Na's, however, and each one is 1+, however, so the Na₂ has a total charge of 2+. Because of this, the 2+ from the 2 Na's and the 2- from the O cancel each other out to make 0.
I hope this helps answer your question. :)
These problems are very hard to do digitally so I would recommend trying to practice these types of problems on paper :)
