It's 53, because the number of protons equal the element's atomic number. You can easily find it on a Periodic Table.
What else can I help you with?
What is an atom compromise of?
An Atom is composed of Electrons,Protons,and Neutrons.
The mass number of an atom is found by adding the?
The mass number of an atom is found by adding the number of protons and neutrons in its nucleus. It is an integer value that represents the total number of nucleons in the atom.
The mass number is used to calculate the number of?
protons and neutrons in an atom. It is the sum of protons and neutrons in the nucleus of an atom.
What is the atomic number for iodine-131?
The atomic number is the same as the number of protons in the nucleus of the particle. Therefore, every atom, ion, and isotope of iodine has an atomic number of 53 (regardless of its mass number).
The mass number of an atom of calcium with 20 protons and 20 neutrons is?
The mass number of an atom is the sum of the protons and neutrons in its nucleus. Therefore, for an atom of calcium with 20 protons and 20 neutrons, the mass number would be 40.
What is the mass number of an atom of iodine with 76 nuetrons?
The mass number of an atom is determined by the number of neutrons and protons. Since you already know the number of neutrons, you just need the number of protons, then you can add them together. I happen to know that iodine has 53 protons, so that means that the mass number is 127.It is the protons and neutrons added together so when you add 53 and 74 you get 127! Hope that helped a lot!! :):):):):):):)
How many protons neutrons and electrons are in iodine?
Iodine has an atomic number of 53, which means it has 53 protons and, in a neutral atom, also 53 electrons. The most common isotope of iodine, iodine-127, has 74 neutrons (127 - 53 = 74). Therefore, in a neutral iodine-127 atom, there are 53 protons, 53 electrons, and 74 neutrons.
Where are protons and neutrons in a atom?
The protons and neutrons are to be found in the atomic nucleus.
Where are protons and neutrons located in?
All the protons and neutrons are located in the nucleus (center) Protons are positvely charged (red) neutrons are green, electrons are negatively charged and yellow
Within an atom protons and neutrons are found in the?
Protons are found in nucleus, as neutrons are also.
Where are the protons and neutrons found in an atom?
Protons and neutrons are normally found in the atomic nucleus.
How many neutrons are there in iodine?
Number of neutrons = Mass number - Number of protons = 127 - 53 = 74
How many protons electrons and neutrons does iodine have?
This question is incomplete. One cannot say how many neutrons an atom of iodine has unless one also specifies which isotope of iodine one is referring to. Since the atomic number of iodine is 53, that means that there are 53 electrons and 53 protons in the neutral atom.
Protons and neutrons are found in this part of an atom?
Protons and neutrons are found in the nucleus of an atom. These subatomic particles "bond" together during fusion to create the nucleus.
Is the proton of an atom found in the nucleus?
Yes protons and neutrons are found in the atomic nucleus.
Where are neutrons and protons found in a atom?
In the atom's nucleus.
Where in the atom are neutrons?
Neutrons can be found in the centre of the atom (the nucleus), along with protons.
