Answer: 15
Explanation:
To find the atomic mass, you add the number of protons and neutrons. The number of electrons is the same as the number of protons
Answer:
The composition of a nuclide (atomic nucleus) is defined by the number of protons Z and the number of neutrons N, which sum to mass number A.Proton number Z, also named the atomic number, determines the position of an element in the periodic table.The approximately 3300 known nuclides are commonly represented in a chart with Z and N for its axes and the half-life for radioactive decay
Explanation:
Answer:
Cl2(g) (green/yellow mix) + 2KBr(s) (white) ---> 2KCl(s) (violet) + Br2(g) (reddish brown)
This chemical reaction is a redox type.
Explanation:
Look at the oxidation state, when the number increase your element gets oxidated, when the number decrease, the elements it's getting reduced.
