<u>Answer:</u>
The element is Chromium.
<u>Explanation:</u>
The atom has 24 protons and 12 neutrons.
We know that Cr has 24 number of protons, to the Chemical is Cr (Chromium)
Again, we know that the atomic number is the number of protons and the atomic mass is the sum of proton and neutron.
So, the atomic number is 24 and the atomic mass is (24+12)= 36
Therefore, the symbol is 
Answer:
b
Step-by-step explanation:
Answer:
D.
Step-by-step explanation:
If you would rotate RN until R meets L it would exactly overlap with FL. So RN=FL.
Answer: the 2 integers are 15 and 17
Step-by-step explanation:
Let x represent the hypotenuse of the right angle triangle. Since the hypotenuse and the other leg are odd consecutive integers, then the other leg is x - 2 because x is longer
When a right angle triangle is formed, it means that
Hypotenuse² = opposite side² + adjacent side²
If the shortest side is 8, it means that
x² = (x - 2)² + 8²
x² = x² - 2x - 2x + 4 + 64
x² - x² + 2x + 2x = 68
4x = 68
x = 68/4 = 17
Therefore, the length of the other leg is
x - 2 = 17 - 2 = 15
