How many protons can the third shell hold?
eighteen
The shell closest to the nucleus, 1n, can hold two electrons, while the next shell, 2n, can hold eight, and the third shell, 3n, can hold up to eighteen.
How many electrons can fit into the 3rd Pan shell?
So the third shell can be considered to hold 8 or 18 electrons but in total the third shell can hold 18 electrons.
Why is there only 8 electrons in 3rd shell?
The maximum capacity of a shell to hold electrons is 8. The shells of an atom cannot accommodate more than 8 electrons, even if it has a capacity to accommodate more electrons. According to this rule, atoms gain, loose or share electrons to achieve the stable configuration similar to the nearest noble gas.
Why does the number of electrons in the third shell suddenly change from 8 to 18?
Look at the periodic table and the Table of Electron Shells handout. Explain why the number of electrons in the third shell suddenly changes from 8 to 18 between the element calcium, Ca, and Gallium, Ga? Because there are 10 euments between Ca and Ga. 8.
Can there be more than 8 electrons in a shell?
So, the concept of a shell is not at all limited to 8 electrons. In fact, this is the maximum number of electrons only for the second shell! A shell with a high value of n has a great any orbitals within it, and can hold many electrons.
How many electrons can fit in the second shell?
This shell can contain a maximum of two electrons. The second shell can hold a maximum of eight electrons. When this is filled, electrons go into the third shell, which also holds a maximum of eight electrons. Then the fourth shell begins to fill.
How many electrons does the outermost shell of an atom hold?
Subsequent shells can hold more electrons, but the outermost shell of any atom holds no more than eight electrons. The electrons in the outermost shell play an important role in bonding between atoms. Elements that have a full outer shell are inert in that they do not react with other elements to form compounds.
How are electrons arranged in the electron shell?
Electron shells. Electrons are arranged in different shells around the nucleus. Each successive shell can only hold a certain number of electrons. The innermost shell is filled first. This shell can contain a maximum of two electrons. The second shell can hold a maximum of eight electrons.
How are protons and electrons different from each other?
The negative charge of one electron balances the positive charge of one proton. Both protons and neutrons have a mass of 1, while electrons have almost no mass. The element hydrogen has the simplest atoms, each with just one proton and one electron. The proton forms the nucleus, while the electron orbits around it.
