Atomic number 75?
Arsenic (As) has 33 protons, giving it an atomic number of 33 and, in it's most common isotope, it has 42 neutrons. Atomic mass is equal to (number of protons + number of neutrons). 33 + 42 = 75.
What is the period number of Rhenium?
In the periodic table, rhenium is number 75.
What is the average neutrons in ununpentium?
For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope – atomic number
What is Rhenium texture?
Rhenium is a chemical element, metal, rare, very expensive.
What is the atomic number of rhenium?
Rhenium, with the chemical symbol Re, is the chemical element with the atomic number 75.
What are the properties that make up mass?
the number of protons plus the number of average neutrons (average number of neutrons in all the different varities of isotopes)
What is the average number of neutrons for roentgenium?
For each isotope of Rg the number of neutrons is different.Number of neutrons = Mass number of an Rg isotope - 111
What is the average number of neutrons in carbon?
6 neutrons. you take the mass, and subtract the atomic number.
How many protons are in rhodium?
Rhenium has 75 protons, 75 electrons and 111 neutrons.The number of protons is equal to the number of electrons.Neutrons can be calculated by subtracting the number of protons from the atomic weight.In this case atomic number is 186 ==> the nr of neutrons = 186-75=111.
What does re stand for in the periodic table?
Re stands for rhenium on the periodic table. Rhenium is a transition metal with the atomic number 75.
How can you use the periodic table to determine the average number of neutrons and elements has even though the number of neutrons is not listed?
To determine the average number of neutrons in an element using the periodic table, first locate the element's atomic mass (usually a decimal number) and its atomic number (a whole number). The atomic number represents the number of protons, while the atomic mass is approximately the sum of protons and neutrons. By subtracting the atomic number from the atomic mass and rounding to the nearest whole number, you can estimate the average number of neutrons for that element.
What is the average number of neutrons found in the nucleus of each atom of atom of gold?
Gold's atomic number is 79 and its atomic mass is 197 (on avarage) 197-79=118 neutrons.
