fluorine is a non metal element. Atomic number of it is 9.
Fluorine is a non meta element. Atomic number of it is 9.
The atomic number is the number of protons. It is also the number of electrons. The atomic mass equals the protons and neutrons together/weight of the nucleus. So, the atomic number would be nine, because there are 9 protons. The atomic mass would be around 19, because there would be 9 protons and 10 neutrons in the nucleus. The element you are talking about is actually Fluorine, and on the periodic table it says that the atomic mass is 18.9984032. This is because the atomic mass is usually never an exact amount. You can round this decimal place to 19, anyway.
The atomic number of an element is the same regardless of its ionic charge. Fluorine has an atomic number of 9, meaning it has 9 protons in its nucleus. Therefore, the atomic number of a negative fluorine ion is still 9.
The atomic number of fluorine is 9.
The atomic number for an element corresponds to the number of protons in its nucleus. Fluorine has 9 protons in its nucleus, which gives it an atomic number of 9. This unique number defines fluorine as an element on the periodic table.
The atomic mass is the same as the atomic weight therefore it is 9.01218. Beryllium is a non metal element. Atomic mass of it is 9.01. The atomic mass number, which is distinct from the atomic mass and the atomic weight, is 9.
the atomic number for fluorine is 9
The atomic number of fluorine is 9.
In an uncharged atom, the number of electrons is always equal to the atomic number, in this instance, 9.
According to the periodic table: F atomic number 9, atomic mass of 18.998403
The atomic number of fluorine is 9, which indicates the number of protons in its nucleus. The atomic mass of fluorine is approximately 18.99 atomic mass units, which is the average mass of an atom of fluorine taking into account its isotopes.
Fluorine is a non meta element. Atomic number of it is 9.
Neutrons have the same mass as a proton but lack an electrical charge. The number of neutrons can be found by subtracting the atomic number, or number of protons in the atom, from the atomic weight. This is calculated this way because the atomic weight represents both the number of protons and neutrons. Fluorine's atomic number is 9 and its atomic weight is 18.998, so 18.998-9= 9.998. Consequently, 9.998 is fluorine's number of neutrons.
The atomic number of fluorine is 9.The atomic number of sodium is 11.
Fluorine is a halogen gas. 9 is the atomic number.

The number of electrons is always the same as the atomic number. That gives you the number of protons and electrons. The atomic mass has nothing to do with it. What is the atomic number? That is your answer.
