How are electron shells filled in sodium?
In sodium (Na), which has an atomic number of 11, the electron configuration is 1s² 2s² 2p⁶ 3s¹. This means that the first shell (1s) is filled with 2 electrons, the second shell (2s and 2p) is filled with 8 electrons, and the third shell (3s) contains 1 electron. Electrons fill the shells starting from the lowest energy level (1s) and move to higher levels (2s, 2p, and then 3s) until all 11 electrons are accommodated. Sodium's single valence electron in the 3s shell makes it highly reactive, as it tends to lose that electron easily.
What do alkali metals need to complete their octets?
Alkali metals have one electron in their outermost shell, which makes them eager to lose that electron to achieve a stable electronic configuration similar to the nearest noble gas. By losing this single electron, they can complete their octet in the next lower energy level, resulting in a filled outer shell. This tendency to lose an electron makes alkali metals highly reactive and able to form positive ions (cations).
How do the electron arrangement differ between the alkai metals and the nobal gases?
Alkali metals have a single electron in their outermost energy level (valence shell), which makes them highly reactive as they tend to lose that electron easily to achieve a stable electron configuration. In contrast, noble gases have full outer electron shells, meaning their valence levels are completely filled with electrons, making them stable and mostly unreactive. This fundamental difference in electron arrangement is the reason behind the contrasting chemical properties of these two groups in the periodic table.
The outer energy level of a noble gas is?
The valence shell (outermost energy level) of a noble gas is filled in ... ns2 np6 electron configuration except helium where it is 1s2.
The group that has one electron in its outer level?
This group is known as the alkali metals, and they consist of elements in Group 1 of the periodic table such as sodium and potassium. Having one electron in their outer level makes them highly reactive and eager to lose that electron to achieve a stable electron configuration.
What makes a happy atom?
a happy atom is an atom with all its electron shells completely filled

Does potassium have more electrons than neon?
No, neon has 10 electrons while potassium has 19 electrons. Neon has a full outer electron shell with 8 electrons, making it stable. Potassium has a partially filled outer electron shell, which makes it chemically reactive.
The outer energy level of a noble gas is?
The valence shell (outermost energy level) of a noble gas is filled in ... ns2 np6 electron configuration except helium where it is 1s2.

How is helium similar to group two elements?
Helium is similar to group 2 elements because it is a noble gas, meaning it has a full outer electron shell which makes it stable and unreactive. Group 2 elements also have stable electron configurations with filled s orbitals in their outermost energy level.
Explain the effect in stability in ships when tank is partially filled with liquid?
It makes the ships center of gravity sink lower in the water. This makes the ship more stable by making it less top heavy and by displacing more water. It gives it a larger base. Hooweestik.
What is the electron configuration for a element that's not chemically reactive?
The rule is that all of the orbitals (respectively - all of shells and blocks) of the element must be filled with their maximum number of electrons.Such phenomenon is observed in the noble gases (group VIII A) - their last blocks - s and p are filled with the total number of 8 electron (2 for s and 6 for p).For instance - The Argon (Ar) has 18 electrons and its configuration is:1s22s22p63s23p6
What feature of Ne makes is a noble gas?
Neon's feature that makes it a noble gas is its full outer electron shell, which makes it very stable and unreactive. This stable configuration means that neon does not readily form chemical bonds with other elements.
Why are noble gases chemically inactive?
The noble gasses all have a filled outer electron shell of eight electrons, except helium which has two electrons. Since their outer electron shells are filled, they are less likely to react with other atoms.
