Find the Number of protons neutrons and electrons in xenon?
Xenon has 54 protons, 77 neutrons, and 54 electrons.
What number is exactly between 54 and 77?
65.5 is the answer. You could get it by adding the two numbers and dividing the sum by 2.
What percent of 77 is 54?
54 is 70.13% of 77.
Can 54 go into 77?
54 doesn't go evenly into 77. 54 goes into 77 once with a remainder of 23.
An isotope of xenon has an atomic number of 54 and contains 77 neutrons. What is the mass number of the xenon isotope?
The mass number is the sum of the number of protons and neutrons in an atom. Since xenon has an atomic number of 54, it has 54 protons. Adding the 77 neutrons to this gives us a total of 131 nucleons (protons + neutrons), making the mass number of this xenon isotope 131.
An atom of an element has 54 protons some of the elements atoms have 77 neutrons while other atoms have 79 neutrons what are the atomic numbers and mass numbers of the two types of atoms of this el?
The atomic number for an element with 54 protons is 54. For the atoms with 77 neutrons, the mass number would be 54 (protons) + 77 (neutrons) = 131. For the atoms with 79 neutrons, the mass number would be 54 (protons) + 79 (neutrons) = 133.
What is the greatest common factor of 54 and 77?
The GCF is 1.
What number is between 66 and 77?
the real numbers between 66 and 77 are (66,67,68,69,70,71,72,73,74,75,76,77)
What is -54 minus 23?
(-54) - 23 = -77
How many protons neutrons and electrons are in xenon?
The protons and neutrons are packed together in the middle and the electrons have space to move, around them. logically their should be MORE neutrons and protons,but this depends on the size of the atom and how many atoms in the neon. info from SUSSEX UNIVERSITY.
A school has 77 girls and 23 boys If N girls leave the school then the percentage of girls will become exactly 54 percent Determine the value of N Assuming that no boys left the school?
The percentage of girls started at 77% and dropped to 54% with no boys leaving. As the total number of students was 100, 54% means there are 54 girls still there. As 77 minus 54 is 23, that is how many girls left. N=23.
What number comes between 77 and 90?
78 - 89 are the numbers that come between 77 and 90.
