Something that can not be undone. Like baking bread..cant be undone.
Explanation:
Atomic size gradually decreases from left to right across the periodic table because within a period of elements, all electrons are added to the same shell. However, at the same time, protons are being added to the nucleus, making it more positively charged. The effect of increasing proton number is greater than that of the increasing electron number. Therefore, there is a stronger nuclear attraction. This means that the nucleus attracts the electrons more strongly, pulling the atom's electron shells closer to the nucleus. As a result, the atomic diameter of the atom decreases.
Answer:
7.1 moles Cl₂
Explanation:
To solve this problem we will use <em>Avogadro's number </em>(Aₙ), which tells us how many molecules (or atoms) are present in 1 mol of any given substance
Aₙ = 6.023 x 10²³ molecules/mol
With that in mind now we proceed to convert molecules into moles:
4.28 x 10²⁴ molecules Cl₂ ÷ 6.023 x 10²³ molecules/mol = 7.1 moles Cl₂
Answer:
The second quantum number, known as the angular or orbital quantum number, describes the subshell and gives the magnitude of the orbital angular momentum through the relation. In chemistry and spectroscopy, ℓ = 0 is called an s orbital, ℓ = 1 a p orbital, ℓ = 2 a d orbital, and ℓ = 3 an f orbital.
