We can find fluorine as a non metal element. Atomic number of it is 9.
Symbol - F Atomic Number - 9 Mass Number - 19
The number of protons determines the atomic number. Since there are for protons, the atomic number is four, and the element is beryllium, symbol Be. The atomic mass number is the number of protons plus neutrons, so in this case it is 9. There are an equal number of protons and neutrons, so there is not charge. The symbol looks like this:94Be
The isotope symbol for fluorine with 9 neutrons is ^18F, where 18 is the atomic mass number (protons + neutrons) and F is the chemical symbol for fluorine.
A fluorine ion with atomic number 9 and 10 electrons has a charge of -1 because it has one extra electron as compared to the number of protons (10-9 = 1). Its symbol is F-.
Co
Symbol - F Atomic Number - 9 Mass Number - 19
According to the periodic table: F atomic number 9, atomic mass of 18.998403
Symbol: F Atomic Number:9 Atomic mass: 18.998 Mass Number: 19 Number of Protrons: 9 Number of Electrons: 9 Number of Neutrons: 10
It contains 10 protons and 10 electrons (no. of protons =no. of electrons in ground state) Number of neutrons=Mass number of element- number of protons =19-10 =9
Fluorine is a non meta element. Atomic number of it is 9.
The atomic number of iridium is 77. Its symbol is Ir. It is placed in group-9 and period -6 in the periodic table.
Fluorine is a chemical element of the Periodic Table, with the symbol F and the atomic number 9.
The number of protons determines the atomic number. Since there are for protons, the atomic number is four, and the element is beryllium, symbol Be. The atomic mass number is the number of protons plus neutrons, so in this case it is 9. There are an equal number of protons and neutrons, so there is not charge. The symbol looks like this:94Be
The isotope symbol for fluorine with 9 neutrons is ^18F, where 18 is the atomic mass number (protons + neutrons) and F is the chemical symbol for fluorine.
A fluorine ion with atomic number 9 and 10 electrons has a charge of -1 because it has one extra electron as compared to the number of protons (10-9 = 1). Its symbol is F-.

It's to the Wikipedia post, and each element is a hyperlink to the post on that element. Bookmark this bad boy, and the periodic table of elements at Wikipedia, too. The periodic table there is interactive, just like this list. And both are a boon to the study of school chemistry. Bookmark them for 30 days and try them out. You can always dump them later, but the benefits you'll derive in just one use will verify their worth. Promise.
