This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
17, unless it is an ion.
it has 18
Periodic table is an arrangement of elements. Chlorine is an element and hence it is there on the periodic table.
they have the same number of electrons
Chlorine
Group 17 of the Periodic Table are the Halogens: Fluorine, Chlorine, Bromine, Iodine, and Astatine. They are very reactive because they are only 1 electron away from the Noble Gas (8 electrons in the outermost shell) state.
Ci means chlorine in the periodic table
Element 17 in periodic table is Chlorine. Chlorine is a halide with 7 valent electrons.
Chlorine is in Group 17 of the Periodic Table.
An oxygen atom contains 8 protons, 8 neutrons and 8 electrons. From 8 protons and 8 neutrons ; 8 + 8 = 16 the atomic mass of oxygern. The this the most common isotope of oxygen .
Periodic table is an arrangement of elements. Chlorine is an element and hence it is there on the periodic table.
Chlorine is in Group 17 of the Periodic Table.
Halogens (Fluorine the most, followed by chlorine).
they have the same number of electrons
Chlorine itself is an element. It is on the Periodic Table (of the Elements). It is made from protons, electrons and neutrons.
The element chlorine has seven electrons in its valence shell.
Halogens have 7 valence electrons. They can be found on the second column from your right on the periodic table
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.
