How many electrons are in an atom of Cl?
There are 17 electrons present in a chlorine atom.
How many protons does the element chlorine have?
Chlorine (Cl) has atomic number 17, and so it has 17 protons in the nucleus.
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.
How many electrons does chlorine as shown on the periodic table have?
Chlorine has 17 electrons. It is displayed as atomic number in periodic table.
How many neutrons and electrons are in the element chlorine?
Each chlorine atom contains 17 electrons, which offset the electric charge of the 17 protons in the nucleus of each atom, as indicated by the fact that the atomic number of chlorine is 17. The number of neutrons per atom varies, however, depending on which isotope of chlorine is examined. There are two naturally occurring and radioactively stable isotopes of chlorine, with mass numbers of 35 and 37, and there are many other radioactive isotopes. The number of neutrons in an atom of a particular isotope may be found by subtracting 17, the atomic number of chlorine, from the mass number.
How many are there electrons in Chlorine?
Chlorine has 17 electrons. The number of electrons in an electrically neutral atom is equal to its atomic number (the number of protons in the nucleus of the atom). The electronic configuration of chlorine is [Ne] 3s2 3p5.
How would you use the Periodic Table to find out how many electrons are in a chlorine atom?
Look at the atomic number. That is the number of protons. Assuming a non-ionic form of Chlorine, that is also the number of electrons.
How many electrons does chlorine have in it's outer shell?
Chlorine is a chemical element with the symbol Cl and an atomic number of 17. It has 7 electrons in its outer shell.
How many total electrons are present if the atom is electrically neutral in chlorine?
A neutral chlorine atom has 17 electrons. You can know this because chlorine's atomic number is 17, which is the number of protons in the nuclei of its atoms, and a neutral atom has equal numbers of electrons and protons.
How many protons are in the element chlorine?
the number of protons for the element chlorine is 17
How many electrons are in an atom of Cl?
There are 17 electrons present in a chlorine atom.
How many protons does the element chlorine have?
Chlorine (Cl) has atomic number 17, and so it has 17 protons in the nucleus.
How many valence electrons are in Cl atom?
There are 7 valence electrons in a chlorine atom. The atomic number of chlorine is 17, which means it has an electron configuration of 2,8,7. This shows it has 3 shells of electrons, with 7 in the outer level.
How many electrons and protons are there in chlorine gas?
Each atom of chlorine has 17 each of protons and electrons; as shown by the atomic number of chlorine.
How many protons neutrons and electrons are in chlorine 39?
The number of protons and electrons is always the same as the atomic number, which for chlorine is 17. The number of neutrons is always the mass number minus the atomic number, which for this isotope is also 17.
How many protons are in the atom chlorine?
Atomic number is equal to the number of protons. The atomic number of chlorine is 17. So chlorine has 17 protons.
Why is chlorine in period 3?
Chlorine is in period three because that is how many outer shells it has. One period is one shell... In the First outer shell you can only hold.. 2 electrons. Second outer shell can hold 10 electrons. Third outer shell can hold 18 electron. Protons + Electrons = Atomic Number Atomic Number - Atomic Mass = Number of Neutrons in Outer Shells
