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.
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.
How do you draw a model of the atomic box with atomic number 16 symbol Si and atomic weight 28.0855?
The element with the symbol Si is silicon with the atomic number 14. The element with the atomic number 16 is sulfur with the symbol S. Not sure about the atomic weight.
How is the atomic mass of an element used to determine the number of nuetrons in its atom?
Different isotopes of the same element have different numbers of neutrons but the same number of protons. The sum of the protons and neutrons is called the mass number. If you know the mass number and the number of protons (which is the atomic number), then you simply subtract the protons (or atomic number) from the mass number and the result is the number of neutrons. Example: Carbon-14 has a mass number of 14. Carbon's atomic number (and number of protons) is 6. So, 14 - 6 = 8 neutrons.
How do you determine neutrons?
take nitrogen as an example it has an atomic number of 7 that determines the number of protons as 7 positive charges so it takes 7 negative charges (electrons) to even it out so you have 7 electrons and protons. then you take the atomic mass which is 14.01 but you can round it to 14. then you take the atomic number and atomic mass and subtract them (14-7=7) so the number of neutrons is 7.
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 the mass number in nitrogen?
Nitrogen is a non metal element. Atomic mass of it is 64.
What is the normal phase os silicon?
Silicon's symbol is Si, and has an atomic number of 14 and atomic mass of 28.086 atomic mass units. Its normal phase is solid.
What is silicon's atomic number and atomic mass?
Si atomic number is 14. Atomic mass is 28.
What is the atomic number of carbon 14?
Carbon is a non metal element. Atomic mass number of it is 12.
What is the mass number and atomic number of nitrogen?
Mass number: 14 Atomic/proton number: 7 If you look at the periodic table, the mass number is the top and the atomic number is the bottom number.
Which element has atomic number as 14?
silicon is the only element with an atomic number of 14. (Si is the symbol on a periodic table)
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.
