Answer:
To determine how many electrons fit in each energy level, use the formula:
2n²
N is equal to the number of energy levels. Using this formula, we can determine that there are:
- First energy level holds 2 electrons
- Second energy level holds 8 electrons
- Third energy level holds 18 electrons
- Fourth energy level holds 32 electrons
- And so on...
Keep in mind though, that for an atom's outermost shell, it can only contain 8 valence electrons due to the octet rule that states that an element only needs eight electrons in their outermost shell in order to be stable.
Answer:
7.52 x 10²³ molecules N
Explanation:
multiply 1.25 mol of N2 by Avogadro's Number
Answer:
Sodium Hydroxide is an ionic compound formed by two ions, Sodium Na+ and Hydroxide OH− . In order for these two polyatomic ions to bond the charges must be equal and opposite. Therefore, it take one +1 sodium ions to balance the one -1 hydroxide ion. This will make the formula for Sodium Hydroxide NaOH
