6 shells.
The first row on the Periodic Table has 1 shell
The second row has 2 shells
The third row has 3 shells
...
The seventh row has 7 shells.
You get the idea :)
same number as the number of protons, unless it is an ion of the element
Radium (Ra) # 88th element in the periodic table.
Whereas the vertical columns on the periodic table are called "groups", and represent the number of electrons in an element's outermost electron shell (eg. group 2 elements have twoelectrons in their farthest energy level), the horizontal rows, known as "periods", refer to the number of energy shells surrounding the nucleus of an element.
The number of shells in periodic table increase down the group, i.e., vertically.
column 6a of the periodic table
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
it has 6 electron shells as it is in the sixth period on the periodic table.
Osmium
Radon
Curium
Dysprosium
The sixth element of the periodic table is Carbon with an a symbol of C, an atomic number of 6 and an atomic mass of 12.0107carbon
Its in seventh period, sixth element.
The element with atomic number 99 on the Periodic Table is Einsteinium. It has the symbol Es and has 6 electron shells. It is synthetic and therefore man-made.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
seaborgium, Sg. See related link.
Radium (Ra) # 88th element in the periodic table.
YES!!! The atomic No. is the postition of the element in the periodic table. It also indicates the number of protons in the element and electrons in the neutral element. The Atomic Mass is also included in the periodic table. The Atomic Mass is the sum of all the protons and neutrons of an element in the periodic table. Here are some examples. Hydrogen ; [1/1]H The first element in the table Carbon ; [12/6]C The sixth element in the periodic table Oxygen ; [16/8]O The eighth element in the periodic table et.seq., The first number given is the Atomic Mass and the second number is the Atomic Number.
