What is Atomic number 9 is?
Fluorine is a non metal element. Atomic number of it is 9.
What is the atomic number of an element whose atoms have 9 protons and 10 neutrons?
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.
Why is the atomic number for fluorine 9?
Fluorine is a non metal element. Atomic number of it is 9.
How many protons are represented in an atom which has an atomic number of 9 and an atomis mass of 19?
An atom with an atomic number of 9 has 9 protons; that's what the atomic number is, it tells you the number of protons in the nucleus.
What is the atomic number of an atom with mass number 9 and 5 electrons?
The atomic number is the number of Protons The mass number is the number of Protons and Neutrons The number of Electrons always equals the number of Protons Therefore according to the above information the atomic number of the atom is 5 HOWEVER there is NO element with a mass number (atomic mass) of 9 with an atomic number of 5. You question is impossible to answer. Beryllium has an Atomic mass of 9.0122 and an Atomic number of 4 Boron has an Atomic mass of 10.811 and an Atomic number of 5
What is the Mass number in beryllium?
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.
Fluorine is 18.99 and atomic number is 9?
Fluorine is a none metal element. atomic number of it is 9.
Fluorine has an atomic number of 9 and an atomic weight of 19 so how many electrons are present in an uncharged fluorine atom?
In an uncharged atom, the number of electrons is always equal to the atomic number, in this instance, 9.
What is fluorine's number of neutrons?
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.
What is symbol atomic number atomic mass of fluorine?
According to the periodic table: F atomic number 9, atomic mass of 18.998403
What is the atomic number of F plus the atomic number of Na?
The atomic number of fluorine is 9.The atomic number of sodium is 11.
What is the atomic number of 19F?
The atomic number of fluorine is 9.
What is the atomic number for fluorine?
the atomic number for fluorine is 9
What is Atomic number 9 is?
Fluorine is a non metal element. Atomic number of it is 9.
Atomic number for fluorine?
Symbol: F Atomic Number:9 Atomic mass: 18.998 Mass Number: 19 Number of Protrons: 9 Number of Electrons: 9 Number of Neutrons: 10

How many electrons are in atomic mass of 19?
Fluorine is the element with atomic weight closest to 19 amu. Fluorine has an atomic number of 9, so an electrically neutral fluorine atom would have 9 electrons.
