The atomic number of an element tells you how many electrons there are and how many protons there are.
The neutral atom of fluorine has 9 electrons.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
If you can find a dot diagram, look at the outer shell and count the electrons. The outer electrons is the amount of valence electrons.
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
Carbon-13 is an isotope. The number of electrons and protons remain the same, only the amount of neutrons changes. you can use this equation to help you : mass#=#p++#n0. the atomic # doesnt change! So, the atomic mass of carbon-13 is 13, and the atomic number is still 6. the amount of electrons stays the same. and the amount of protons is subtracted from the mass # to find the amount of neutrons. so electrons=6, protons=6, and neutrons=7.
Beryllium, or Be, has two electrons in both the first and second shell. The atomic number is 4 if you need to find it on the periodic table.
The # of electrons is the same are the # of protons.
An atom of fluorine has 9 electrons in total. Electrons are equal to protons when the atom isn't an ion, and the number of protons is also the atomic number of the element, so you just need to know the atomic number to find out the number of electrons or protons.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
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
If you can find a dot diagram, look at the outer shell and count the electrons. The outer electrons is the amount of valence electrons.
To find out the number of electrons in an element you must add the protons and neutrons and subtract that number with the atomic mass, this will determine the amount of electrons because the unknown element could be an isotope and have more than the normal amount of electrons of the non isotope element.
The number of protons is the same as the atomic number, which is nine in this case. If the atom is neutral, then the number of electrons will balance the number of protons, also nine in this case. Usually, the number of neutrons will vary with the isotope (atoms with a different number of neutrons) however, fluorine has only one natural isotope, 18F, with nine neutrons.See link below for more information on fluorine, as well as the related question below that will show you how to find the number of each subatomic particle in any atom.
The atomic number of the element is the number of protons, therefore there has to be the same amount of electrons to protons.
16 ... if it's not ionized. A neutral atom would have 16 electrons, one negative charged electron for each positive charged proton. Now an atom does not have to be neutral, it can have more or less electrons, which is called an ion. 16 Protons would make this a Sulfur atom, which is going to try to aquire 2 more electrons to have a complete orbital shell.
Rate of change = amount of change in some period of time/amount of time for the change
Electrons are the same thing as protons so, you would look at the first # in the square "Atomic Mass" andthere's your awnser.
