Which p-block element has 4 valence electron and is in the third period?
Silicon is p-block element. It has 4 valence electrons. It is present in group-14.Titanium has 4 valence electrons. It is in the third period. Titanium is a metal element.
Why you only put 8 electrons in the outer cell of pottassium?
Potassium (K) has an atomic number of 19, meaning it has 19 electrons. The electron configuration of potassium is 2, 8, 8, 1, indicating that it has 8 electrons in its second energy level (the outer shell) and 1 electron in its third energy level. According to the octet rule, elements tend to be more stable with 8 electrons in their outer shell, which is why potassium's configuration shows 8 in the outer shell, even though its valence shell can hold more. The single electron in the third shell is readily lost, making potassium a highly reactive alkali metal.
what element has largest atomic radius in 3rd period elements?
In the third period of the periodic table, sodium (Na) has the largest atomic radius. As you move from left to right across a period, the atomic radius decreases due to increasing nuclear charge, which pulls electrons closer to the nucleus. Sodium, being the first element in the period, has the least effective nuclear charge acting on its outer electrons, resulting in a larger atomic radius compared to the other elements in the third period.
What is the maximum number of electrons that can go into the third period?
The third period of the periodic table can hold a maximum of 18 electrons. This includes filling the 3s, 3p, and 3d sublevels with a total of 8, 6, and 4 electrons respectively.
What is the least electronegative element in the third period?
It is sodium metal.
Which p-block element has 4 valence electron and is in the third period?
Silicon is p-block element. It has 4 valence electrons. It is present in group-14.Titanium has 4 valence electrons. It is in the third period. Titanium is a metal element.
Which has more outer electrons phosphorus or silicon?
Phosphorus has more outer electrons than silicon. Phosphorus has 5 outer electrons in the third energy level, while silicon has 4 outer electrons in the third energy level.
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
Which period contains the element silicon?
The element Silicon (Si) is in the third Period on the Periodic Table. It is also the second element in Group 14(4) - The Carbon Family. It has 14 electrons in 3 shells, with 4 electrons in the outer shell.
How many electrons does Magnesium have in its outer most shell?
Magnesium has a total of 12 electrons. The electron configuration would be 1s2 2s2 2p6 3s2. Therefore, 2 electrons in it's outer shell.
How many electrons are in the outer shell of aluminium?
3 electrons total. electrons is the number on the top right corner with the plus sign indicating that electrons are positive.
What is sulfur of outer electrons?
Sulfur has 6 outer shell electrons, which are located in the third energy level. These electrons are involved in forming chemical bonds with other atoms to complete sulfur's outer shell and achieve a stable electron configuration.

Sodium, being the first element in the period, has the least effective nuclear charge acting on its outer electrons, resulting in a larger atomic radius compared to the other elements in the third period.
How many electron are on the outer shell of a manganese?
Manganese, with an atomic number of 25, has 2 electrons in its first shell, 8 in its second, 13 in its third, and 2 in its fourth outer shell. So, there are 2 electrons in the outer shell of a manganese atom.
What is the maximum number of electrons that can go into the third period?
The third period of the periodic table can hold a maximum of 18 electrons. This includes filling the 3s, 3p, and 3d sublevels with a total of 8, 6, and 4 electrons respectively.
How many outer orbital electrons are found in an atom of p?
An atom of phosphorus (P) has five outer orbital electrons in its third energy level, as it has 15 electrons in total with electronic configuration 2-8-5.
