Answer:
25
Explanation:
Isotopes of an element are the same element with different mass numbers but the same atomic number or the number of protons.
we know that in a balanced atom
Number of electrons = Number of protons = Atomic number
Atomic number (z) of manganese = 25
For Mn+5, the number of protons remains the same = 25
However, the number of electrons on Mn+5 = 21
Answer:
Check explanation section.
Explanation:
Isotopes are chemical species of the same elements with different number of neutrons but the same protons.
Both Chlorine-35 and Chlorine-36 are the same because they are both isotopes of the same elements that is Chlorine. Also, both Chlorine-35 and Chlorine-36 have the same number of protons which has the value equal to 17.
The difference between Chlorine-35 and Chlorine-36 is that Chlorine-35 is stable and has the abundance of 75.77% whole Chlorine-36 is found in trace.
Also Chlorine-35 has a neutrons value of 18 while that of Chlorine-36 is 19.
Hello!! WOW, what a coincidence! I just took this lesson and quiz yesterday, so the answer is still fresh in my mind!
The answer to your question is
D) Blowing sand can wear away a rock's surface and break it into smaller pieces
When wind blows, sure it can pick up dry soil and sand and relocate it, but that doesn't cause the weathering in rocks.
Wind doesn't create new landforms either, that comes from plate tectonic movements and other things.
I just eliminated B and C with the two sentences above, I really don't know how to eliminate A, just common sense i guess.
Please give me brainliest if I was correct and helpful!
Otherwise, please comment and let me know how I can fix my answer!
Thank you, it was fun, have a nice week!
Answer: I think it’s A sorry if I’m wrong
Explanation:
Answer:
B. They all have molecules in motion.
Explanation:
All substances have molecules in motion, this is because all substances have an average kinetic energy (temperature) of over 0 K.
