Mass number = proton number + neutron number SO, Mass number(Aluminium) = 13+ 14 =27
27
The natural stable isotope of silicon, 30Si, has 14 protons and 16 neutrons.
In a neutral atom of fluorine, there are 9 electrons. The number of neutrons varies with an isotope's mass number.
Palladium has 46 protons and electrons. Number of neutrons = Atomic mass of an isotope of palladium - 46
Unundeptium has 117 protons and electrons; the number of neutrons is 176 or 177, depending on the isotope.
Meitnerium has 109 protons and electrons.For each isotope of Mt the number of neutrons is different. Number of neutrons = Mass number of an Mt isotope - 109
Aluminium has 13 electrons and protons; the isotope 27Al has 14 neutrons.
The aluminum atom has 13 electrons and protons and also 14 neutrons.
The natural stable isotope of silicon, 30Si, has 14 protons and 16 neutrons.
14.
If the isotope existed, it would have 16 neutrons.
If the isotope existed, it would have 16 neutrons.
You are probably referring to neutrons which are often found within the nucleus of an atom in numbers different from the protons. An atom of the element carbon, for instance, normally consists of 12 protons, 12 electrons and 12 neutrons. However, an isotope of carbon known as C13 consists of 12 protons, 12 electrons and 13 neutrons.
A nitrogen atom has 7 protons, 7 electrons and 7 neutrons for the most common isotope
Radium has 88 electrons. The number of neutrons is different for each isotope: Number of neutrons = Atomic mass of an isotope - 88
Aluminum has 13 electrons/protons and 14 neutrons.
The isotope that has 13 protons and 14 neutrons is aluminum.
Boron has 5 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a boron isotope = Mass number - 5
