The electron configuration of phosphorus (atomic number 15) is 1s² 2s² 2p⁶ 3s² 3p³. This indicates that phosphorus has two electrons in the 1s subshell, two in the 2s subshell, six in the 2p subshell, two in the 3s subshell, and three in the 3p subshell. The configuration reflects its position in the Periodic Table and its chemical properties.
because they have completely filled orbitals
Noble gases have a stable electron configuration with a full outer shell, making them very unreactive or inert. This property means they rarely form chemical bonds with other elements.
To simplify the expression -5p³(4p² + 3p¹), distribute -5p³ to both terms inside the parentheses. This results in -5p³ * 4p² = -20p^(3+2) = -20p⁵ and -5p³ * 3p¹ = -15p^(3+1) = -15p⁴. Therefore, the final expression is -20p⁵ - 15p⁴.

On, flouride gains an electon when it ionizes.
because they have completely filled orbitals
5p + 15p + 7p = 27p 5p - 15p + 7p = -3p 5p x 15p + 7p = 75p2 + 7p 5p/15p + 7p = 7p + 1/3
The expression "15p 40" seems to have a typographical error, as it's unclear whether it's meant to be "15p + 40" or "15p - 40." Assuming it's "15p + 40," you can factor it as 5(3p + 8). If it's "15p - 40," it can be factored as 5(3p - 8). Please clarify if you meant something different!
fraction of 80p is 15p = 15/80 or 3/16
how many different ways can make 15p
15p = 75 Therefore, p = 75/15 p = 5

Noble gases have a stable electron configuration with a full outer shell, making them very unreactive or inert. This property means they rarely form chemical bonds with other elements.
15p/£1 = 15p/100p = 15/100 or 3/20
Sulfur needs to gain 2 electrons to have the electon configuration of Argon
12x+15p-6p+11x = 12x+11x+15p-6p = (12+11)x+(15-6)p = 23x + 9p
