A sodium atom has a mass number of 23 Its atomic number is 11 How many electrons does it have if it is not an ion?
it is 12
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).
What is the formula to get the number electrons?
The number of electrons is the same as the number of protons or the atomic number. If the element is an ion of e.g O+2, you would take away 2 from the atomic number and if it is O-2, you would add two electrons
What number indicates the number of protons in the nucleus of an atom?
The atomic number tells you the number of protons in an atom. The atomic number is right above the element symbol. Example: 36 83.80 In this example, 36 is the atomic number, so the number of protons is 36. Protons and electrons can be found by the atomic number.
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.
What is the identity of an ion with an atomic number is 16 and mass 33 and 18 electrons?
The ion with an atomic number of 16, mass 33 and 18 electrons is the sulfide ion S2-
Why do you calculate the number of electrons by the atomic mass and number?
because an atomic number is the same as the number of electrons in an atom (not ion)
A sodium atom has a mass number of 23 Its atomic number is 11 How many electrons does it have if it is not an ion?
it is 12
An ion of iron has an 26 protons 30 neutrons and 23 electrons. What are its atomic number atomic mass and net charge?
Atomic number : 26Atomic mass : 55.845 Net charge : +3
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 formula used to calculate the number of electrons when only the atomic number is given?
The number of electrons is simply the same as the atomic number, assuming the compound or element is neutral (not positive or negative). To find the number of neutrons, take the atomic mass and subtract atomic number. The number of electrons is simply the same as the atomic number, assuming the compound or element is neutral (not positive or negative). To find the number of neutrons, take the atomic mass and subtract atomic number.
How do you solve for neutrons?
You need to know the charge on the atom or ion. The mass number is completely irrelevant if you have the atomic number.The atomic number tells you the number of protons in the nucleus.If the atom is neutral, then it has as many protons as electrons, and so the number of electrons equals the atomic numberIf the atom is charged, and is thus called an ion, than take the atomic number and subtract the charge from it to give the number of electrons.For instance, if you have a sodium ion with charge +1 (Na+), then the number of protons is equal to 11 (the atomic number), and the number of electrons is11 - 1 = 10If instead you had a chlorine ion with charge -1 (Cl-), then the number of protons is equal to 17 (the atomic number), and the number of electrons is17 - -1 = 18See the Related Questions to the left for more information about how to count the particles of an atom.
An ion with 5 protons and 6 neutrons has an atomic number of?
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.
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 would you need to tell the number of protons and electrons present in an ion?
The atomic number of the element in the ion, when there is only one such element, and the atomic charge on the ion. For example, in Na+1, the atomic number is 11; this gives the number of protons. The number of electrons is equal to the atomic number minus the charge on the ion, in this instance, 10 electrons. If the sign on the ion is negative, as in O-2, remember that subtracting a negative number is equivalent to adding the positive number of the same magnitude. Thus, oxygen has an atomic number of 8, and 8 - (-2) equals 10 electrons.
A neutral atom has a atomic number of 12 and a mass of 24 how many electrons does it contain?
24. Atomic number is a reflection of the number of protons, which equals the number of electrons in an atom. The number of electrons would vary only if it were an ion, and the number of neutrons would vary only if it were an isotope.
What is the mass number of the ion?
The mass number of an ion remains the same as the element. This is because an ion gains or loses electrons which have minimal mass.
