When considering the atomic number, the only information that we need is the number of protons. To know if the particle is an ion, has more or less electrons, how many neutrons, etc - will not change the atomic number. The atomic number is the same as the number of protons, so in this case, the atomic number of an atom (or ion, doesn't matter) with 5 protons is 5.

∙ 13y agoAtomic Mass number is simply the sum of the atomic number and the number of neutrons. So, the answer is 5 + 6 = 11

How do you calculate the number of protons neutrons and electrons of an atom?
The charge of an ion can be calculated by adding up the protons and subtracting the electrons. When oxygen with 8 protons has 8 electrons it is neutral, when it has 7 electrons it is positively charged.
What is the rule for determining the mass number of an atom or ion?
The mass number is the sum of number of protons and neutrons in the atomic nucleus.
How many protons neutrons and electrons does sodium ion contain?
The simplest way to figure this out is as following: the atomic number of sodium is 11, which gives you the number of protons. The number of electrons = the number of protons. The number of neutrons is the atomic weight (22.98 in this case) rounded minus the number of protons. Therefore sodium has 11 protons, 11 electrons, and 12 neutrons. Hope this helps! :)
How many neutrons are in iodine-127.?
Refer to the Periodic Table. Iodine has atomic Number of 53. This tells us that there are 53 protons in the nucleus. I-127 is the Atomic Mass. The figure is the total of all the protons and neutrons in the nucleus of the atom. So the total number of neutrons will be 127 - 53 = 74 neutrons.
How do you find the number of neutrons protons and electrons in an atom if the atom is neutral?
The number of electrons in an atom is always equal to the number of protons in that same atom. Since the atomic mass of a periodic element equals the weight of the atoms protons AND its neutrons, the following equation can be used to calculate the number of any given particle in an atom: number of neutrons = atomic mass - atomic number

How many protons neutrons and electrons does bromine have?
Bromine has the atomic number 35, which means there are 35 protons in the nucleus of an atom of bromine.The mass number (also known as the atomic mass number) of an element is the sum of the protons and neutrons in the nucleus.Bromine's mass number is 80, so there must be 35 protons and 45 neutrons in an atom of bromine.Sorry we do not know what you mean by "newtrons" or "deos".
What is the rule for determining the mass number of an atom or ion?
The mass number is the sum of number of protons and neutrons in the atomic nucleus.
The atomic number of an atom indicates the number of?
The atomic number is the number of protons in the atom. In the case of a neutral atom (as opposed to an ion), the atomic number is also equal to the total number of electrons.
How many subatomic particles does an ion of calcium with an atomic number of 20 and an atomic mass of 40 hve?
atom have: 20 protons,20 electrons and20 neutrons ion have: 20 protons 18 electrons( metals lose electrons) and20 neutrons

What is the symbol of an ion that has 20 protons 20 neutrons and 18 electrons?
The atomic number always equals to the number of protons. which in this case, is 20

How many protons are in an ion?
The number of protons present in an ion is equivalent to its atomic number.
What is atomic number of neutral atom with 22 electrons and 26 neutrons?
In a neuteral atom no. of electrons=no. of protons no. of protons=22 and atomic number is given by no. of protons=22 Hence Atomic number is 22
How can you determine the number of neutrons in an atom if its mass number and its atomic number are known?
It is impossible to determine the number of neutrons from the mass number and atomic mass, since the two are essentially same value. However, with the atomic number and the mass number, one can calculate the number of neutrons by subtracting the atomic number from the mass number.
