If fluorine has an atomic number of 9 and an atomic mass of 19 how many electrons does fluorine contain?
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.
Atomic number describes what?
Atomic number describes about number of protons.It is equals to number of protons.
How can the number of proton neutron and electron be calculated to get atomic number and atomic mass?
atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number
What is the atomic number of an element?
The atomic number is the number of protons in the nucleus of an atom of an element. An element that is in its neutral state has the same number of protons and electrons, thus the atomic number can also be used to tell the number of electrons in a non-ionic atom of that element.
What three things can the periodic table tell you about an element?
NameAbbreviationAtomic Number (number of protons = number of electrons)Number of neutrons in various isotopesAtomic massValenceGroup
What does atomic number tell you?
Tell you the number of protons and electrons in an atom
What do the atomic number and the mass number tell you about the atom?
the atomic number is the number of protons/electrons in the atom
What do the atomic number and mass number tell you about the atom?
the atomic number is the number of protons/electrons in the atom
What do the atomic number and atomic mass tell you about an atom?
Atomic number tells the number of protons and electrons, but i don't remember for atomic mass.
What does the atomic number tell you about the element?
it tells you the number of protons and electrons
What do the atomic number and mass number tell you about an atom?
Atomic number tells the number of protons and electrons, but i don't remember for Atomic Mass.
What do the atomic number and mass number tell about an atom?
Atomic number tells the number of protons and electrons, but i don't remember for Atomic Mass.
How do you tell how many electrons an element has?
The number of electrons should balance the number of protons, which is denoted by the atomic number.
What is the atomic number of magnesium what does the number tell you?
The atomic number of magnesium is 12. The atomic number tells you the number of protons in the nucleus of the magnesium atom, which also corresponds to the number of electrons in a neutral magnesium atom.
What does the atomic number tell you about the parts of the element?
The atomic number of an element tells you the number of protons and neutrons that element has. Since an atom has a neutral charge, the number of electrons must equal the number of protons, so you can also tell the number of electrons that element has.
How do you find electrons?
you can find electrons by subtract the atomic number and atomic mass.
If an f an atom has 36 electrons and 48 neutrons, then what is the atomic number?
Atomic number= 36 atomic number= no. of electrons
