Answer:
they are molecules with normal bonds rather than partial bonds and can occasionally be isolated.
Explanation:
In chemistry, reaction intermediates are species that are formed from reactants and are subsequently being transformed into products as the reaction progresses. In other words, reaction intermediates are species that do not appear in a balanced reaction equation but occur somewhere along the reaction mechanism of a non-elementary reaction. They are usually short lived species that possess a high amount of energy. They may or may not be isolated.
They are often molecular species with normal bonds unlike activated complexes that are sometimes hypervalent species.
Level 3 is the correct answer
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.
The answer is: a metal cation and the shared electrons that surround it.
Metallic bond is a type of chemical bond.
Metallic bond is formed between electrons and positively charged metal ions.
Metallic radius is defined as one-half of the distance between the two adjacent metal ions.
Metallic bond increace electrical and thermal conductivity.
Metals conduct heat, because when free moving electrons gain energy (heat) they vibrate more quickly and can move around.
