The symbol for an element with a mass number of 28 and an atomic number of 14 is ( \text{Si} ) for silicon. In nuclear notation, it can be represented as ( \text{^{28}_{14}Si} ). This indicates that silicon has 14 protons and 14 neutrons, resulting in a total mass number of 28.

What is the atomic mass of flourine-14?
The atomic mass of fluorine-14 is 14 atomic mass units (amu). It is determined by the total number of protons and neutrons in the nucleus of the fluorine-14 atom.
Do carbon 12 and 14 have the same atomic mass?
No. They have different masses, but the same atomic number. Carbon-12 has a mass number of 12 and atomic number of 6, and carbon-14 has a mass number of 14 and atomic number of 6. The difference in mass number is due to different numbers of neutrons. Carbon-12 atoms have 6 neutrons and carbon-14 atoms have 8 neutrons.
Nitrogen has an atomic mass of 14 and an atomic number of 7 so the number of neutrons must be?
The atomic mass of an atom is the total mass of its particles. The atomic number is the number of protons in the atom's nucleus. To find the number of neutrons in an atom, we take its atomic mass (the total mass of its particles) and subtract its atomic number (the number of protons and electrons in the atom). A: Lithium has an atomic mass of 7 and an atomic number of 3 so the number of neutrons is equal to 4. (7 - 3 = 4)
What are the atomic and atomic mass numbers of nitrogen?
Nitrogen has a gram atomic mass of 14.0067, an atomic number of 7, and the chemical symbol N.
What is a symbol for an isotope that has a mass number of 28 and an atomic number of 14?
Si
What is the symbol for silicon-28?
28/14 Si Its the number they give you which is the atomic mass of the isotope over the atomic number and the symbol of the element.
What is the nuclear symbol and the hyphen notation for a carbon isotope with a mass number of 14 and atomic number of 6?
Note that since all carbon isotopes have an atomic number of 6, it is not necessary to state the atomic number; the fact that it is carbon means that it has the atomic number 6. So the isotope with a mass number of 14 is called carbon 14. As a symbol, it is C with a superscript 14 (which I am not able to type).
Where can you find atomic numbe rand atomic mass in the symbol of element?
The atomic number is usually written to the lower left of the atomic symbol. The atomic mass is usually written to the upper right of the atomic symbol. So, carbon-14 would look like this: 6C14

What is and isotopes natation?
Isotopes notation is a way to represent a specific isotope of an element using the element's symbol along with the mass number and atomic number. The notation typically includes the atomic number as a subscript and the mass number as a superscript next to the element's symbol. For example, carbon-14 is represented as ^14_6C.
