<span>Iron Oxide</span><span> Fe2O3 = 5 atoms.</span>
Answer:
47, 68, 47
Explanation:
Let's consider the following isotope: ¹¹⁵Ag.
If we look in the Periodic Table, the atomic number of Ag is 47, that is, silver has 47 protons.
Since ¹¹⁵Ag is neutral it must have the same number of protons that of electrons. Then, it also has 47 electrons.
The number 115 in ¹¹⁵Ag stands for the mass number, which is the sum of protons and neutrons. Then, the number of neutrons is:
p⁺ + n⁰ = 115
n⁰ = 115 - p⁺ = 115 - 47 = 68
The number of protons, neutrons, and electrons in ¹¹⁵Ag is: 47, 68, 47.
Answer:
A bar graph
Explanation:
a bar graph keeps track of things like the length of something. of course there will be other things that it can keep track of but for your case, you will want to use a bar graph.
I hope that this helps! Best of luck!
