Metallic bonds are formed by the valence electrons from the s and p orbitals of the interacting metal atoms delocalizing.
As you go down the periodic table, electronegativity decreases. As you go across the pt, it increases. It is the same trend as ionization energy.
These are isotopes of that element. The nucleus is different because the number of neutrons differ and aren't the same. The number of protons are the same though.<span />
Answer: e. Number 1 and 3
Reasoning: Correct formulas are necessary to get the correct outcome. No matter is created or destroyed, the equation must be balanced.
The IUPAC names of the organic compounds would be as follows:
1. Methanol or 1-Methanol
2. Propan-2-ol or 2-Propanol
3. 2-MethylButane
4. 1-Hexanol
5. 1-Heptanol
<h3>Naming organic compounds</h3>
In the naming of organic compounds, some fundamental rules come into practice. Some of these rules include:
- The longest carbon chain, otherwise known as the parent chain, is considered.
- The substituents must be identified
- The parent chain should be named such that the substituents are located on the lowest-numbered carbons. Repeated substituents are named accordingly.
- Different substituents are named alphabetically and substituents with lower alphabets are considered for the lowest-numbered carbons.
Following these rules and more, the name of the organic compounds whose structures are shown in the image would be as follows:
- Methanol or 1-Methanol
- Propan-2-ol or 2-Propanol
- 2-MethylButane
- 1-Hexanol
- 1-Heptanol
