One way is to divide 35 by 100 and then multiply that answer by 80. The answer is 28. 35 divided by 100 = 0.35 x 80 = 28
Oh, dude, math time! So, if 28 is 35% of a number, we can set up an equation like 28 = 0.35x and solve for x. Dividing 28 by 0.35 gives us the number, which is 80. Ta-da! Math wizardry at your service.
The number of neutrons is 45 because you subtract 80 to 35.
Divide by 80.
There are 35 protons in bromine-80 (Br-80). This is because bromine has an atomic number of 35, which corresponds to the number of protons in its nucleus.
28.0 (To do this problem, multiply 80 by .35)
35 can be divided by: 1, 5, 7, 35.
28
35 is 80% of 43.75
means divide the number by 35, then double it
79? I'm pretty sure the atomic mass of Bromine is 80. Incase you were wrong, the Atomic mass = Number of protons + Neutrons, which is 80. The atomic number is 35, which is the number of protons. Protons = 35. So the No. of Neutrons = 80 ( protons & neutrons) - 35 (protons) = 45 ( No. of neutrons) and Finally for electrons = the number of protons which is 35.
The element with atomic number 35 is bromine (Br). It has 35 protons and since it is neutral, it also has 35 electrons. To find the number of neutrons, subtract the atomic number (35) from the atomic mass (80). So, bromine-80 has 45 neutrons.
