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.
Atomic Mass number is simply the sum of the atomic number and the number of neutrons. So, the answer is 5 + 6 = 11
11 = 5p + 6n (the electrons are not counted as their mass is roughly 1000 times smaller)
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.
The mass number is the sum of number of protons and neutrons in the atomic nucleus.
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! :)
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.
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
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.
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".
The mass number is the sum of number of protons and neutrons in the atomic nucleus.
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.
atom have: 20 protons,20 electrons and20 neutrons ion have: 20 protons 18 electrons( metals lose electrons) and20 neutrons

The atomic number always equals to the number of protons. which in this case, is 20

The number of protons present in an ion is equivalent to its atomic number.
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.
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
