What is the atomic number of F plus the atomic number of An equals the atomic number of this elements?
There is no element whose symbol is An.
What atomic number of F plus the number of Na equals the atomic number of thos element?
The atomic number of F is 9, Na is 11, so F (9) + Na (11) = 20. The element with an atomic number of 20 is calcium (Ca).
What equals atomic mass minus protons?
Roughly, the number of neutrons. Note that the atomic mass is only approximately equal to the number of protons plus the number of neutrons - there is a relatively small discrepancy, due to the binding energy.
What is the mass number of the isotope of manganese (Mn) containing 28 neutrons?
Go to the periodic table and look up the atomic number of iron (Fe). The atomic number of iron is equal to the number of protons in iron. Mass number is the number of protons plus the number of neutrons so add up the two values.
What is the number of protons plus the number of electrons?
The number of protons plus the number of electrons isn't a recognized figure in chemistry. The number of protons is the atomic number of an element. The number of electrons is the same as the number of protons except when the element is an ion. An ionic compound results in one or more electrons moving from one element to another element. Although this is a simplification, it can be described as the atom gaining or losing electrons. The number of protons plus the number of neutrons is the atomic weight of an element.
What is the atomic number of F plus the atomic number of An equals the atomic number of this elements?
There is no element whose symbol is An.
What atomic number of F plus the number of Na equals the atomic number of thos element?
The atomic number of F is 9, Na is 11, so F (9) + Na (11) = 20. The element with an atomic number of 20 is calcium (Ca).
What is the atomic number of f plus the atomic number of Na equals the atomic number of this element?
The atomic number of F (fluorine) is 9 and the atomic number of Na (sodium) is 11. Adding them together gives 20, which is the atomic number of calcium (Ca).
What the atomic number of F plus the atomic number of Na equals equals the atomic number of this element?
At No(F) + At No(Na) = 20.At No of Calcium = 20.
How do you calculate the atomic number of the given element?
protons plus neutrons = atomic number
How do you find the number of electrons for an element?
It is the same as the number of protons if it is a neutral atom, or the number of protons plus the charge of the ion. The number of protons is the atomic number of the element.
Is the atomic weight of an element is equal to the number of protons minus the number of neutrons?
No, the atomic weight of an element is not equal to the number of protons minus the number of neutrons. Atomic weight is the average weight of an element's isotopes taking into account their abundance, which includes the sum of the protons and neutrons in the nucleus.
What is the number of neutrons in magnesium 24?
The # of nuetrons in any element is the Atomic Mass - the # of protons In this case the atomic mass was 24.3 minus the protons (12) equals 12
What is an atomic number and a mass number?
The atomic number is the number of protons in an atom. This number is fixed and determines what element that atom is. The atomic mass is the mass of an atom and is roughly equivalent to the number of protons plus the average number of neutrons that atoms of that particular element.
What is the element with a plus 35 on its nucleus?
The one with atomic number 35: bromine.
What atomic number of F plus the atomic number of Na equals the atomic number of this element?
Calcium
What is a mass number atomic mass number?
The atomic number is the number of protons in an atom. This number is fixed and determines what element that atom is. The Atomic Mass is the mass of an atom and is roughly equivalent to the number of protons plus the average number of neutrons that atoms of that particular element.
