How many protons and electrons in fluorine?
Fluorine has 9 protons and 9 electrons. The number of protons determines the element's identity, while the number of electrons is equal to the number of protons in a neutral atom.
How to find the amount of valence electrons in an atom?
To find the amount of valence electrons in an atom, look at the group number on the periodic table. The group number tells you how many valence electrons an atom has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
What is the oxidation number of you in IF7?
In IF7, Fluorine is more electronegative than Iodine, so Fluorine will have an oxidation number of -1. Since there are 7 Fluorine atoms bonded to the Iodine atom, their total oxidation number is -7. To find the oxidation number of Iodine, you would set up an equation: I + (-7) = 0. Therefore, the oxidation number of Iodine in IF7 is +7.
What is the density in g L of fluorine gas at 7.00 102 torr and 27.0ºC Molar mass of fluorine equals 38.0 g mol?
To find the density of fluorine gas, we first need to calculate the molar volume of the gas using the ideal gas law equation PV = nRT. From there, we can convert the molar volume to L/mol. Finally, we can find the density by dividing the molar mass by the molar volume. The density of fluorine gas at 7.00 x 10^2 torr and 27.0ºC is approximately 1.5 g/L.
It takes 254 kJmol to eject electrons from a certain metal surface What is the longest wavelength of light nm that can be used to eject electrons from the surface of this metal via the photoelectr?
To find the longest wavelength of light that can eject electrons from the metal surface, we need to use the equation E = hc/λ, where E is the energy required (254 kJ/mol), h is Planck's constant, c is the speed of light, and λ is the wavelength. Rearranging the equation to solve for λ, we find that the longest wavelength of light that can eject electrons is approximately 487 nm.
What is the total number of valence electrons in a fluorine atom you n the ground state?
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.
How many protons and electrons in fluorine?
Fluorine has 9 protons and 9 electrons. The number of protons determines the element's identity, while the number of electrons is equal to the number of protons in a neutral atom.
How many protons electrons and neutrons are in the element fluorine?
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.
How to find the amount of valence electrons in an atom?
To find the amount of valence electrons in an atom, look at the group number on the periodic table. The group number tells you how many valence electrons an atom has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
How do you find the number of protons electrons of an element?
The atomic number of the element is the number of protons, therefore there has to be the same amount of electrons to protons.
What equation do you use to find the rate of change?
Rate of change = amount of change in some period of time/amount of time for the change
If an atom has 16 electrons how many are in the third level?
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.
What is the most non-metallic element?
The most non-metallic element is fluorine. It is a highly reactive, corrosive gas and belongs to the halogen group in the periodic table. Fluorine has a strong tendency to gain electrons and form negative ions in chemical reactions.
How do you find amount of electrons in an atom?
Electrons are the same thing as protons so, you would look at the first # in the square "Atomic Mass" andthere's your awnser.
How do find the amount of electrons in an atom?

How do you find out the amount of electrons in an atom?
The number of electrons in an atom is equal to its atomic number, which is the number of protons in its nucleus. This is because atoms are electrically neutral, so they have an equal number of protons and electrons. You can find the atomic number of an element on the periodic table.
What is the atomic symbol for an element that has 10 neutrons and a mass number of 19?
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
