Can someone please help me with the correct formula for this?
Anarel [89]

Answer:

C₂H₄O

CH₃CHO

Explanation:

I'm not sure if you want the molecular formula or the condensed structure, but I will give you both.

Molecular formula:

You have 2 carbons (C₂), 4 hydrogens (H₄), and 1 oxygen (O).  The molecular formula will be C₂H₄O.

Condensed Structure:

You have a carbon bonded to three hydrogens (CH₃).  This carbon is bonded to a carbon that is bonded to a hydrogen and oxygen (CHO).  The condensed structure will be CH₃CHO.

*40 IF YOU ANSWER CORRECTLY & ADDED BRAINIEST*
Vikentia [17]

Answer:

1. B

2. C

Explanation:

1. There are 15 electrons which means that the element is phosphorus. We know it is in the excited state because an electron from the second ring has moved to the third one, typically it would be 2 - 8 - 5.

2. An element with 3 valence electrons will be 3 spaces from the left side of the periodic table. Sodium is 1, Magnesium is 2, Aluminium is 3, and Silicon is 4. Noble gasses on the right have all 8.

Describe the orbital diagram of an atom with six electrons. Explain how this orbital diagram demonstrates Hund's rule.
densk [106]

Answer:

See explanation

Explanation:

According to Hund's rule, electrons must occur singly first before pairing takes place.

If I want to fill six electrons into orbitals, the filling of electrons will be as follows;

1s2 2s2 2p2.

The first four electrons are filled into the 1s and 2s levels having only one orbital each. The fifth and sixth electrons are filled into 2p orbitals. The 2p level have three degenerate orbitals. The two electrons are singly filled into each of the degenerate orbitals in accordance to Hund's rule.
