Answer:

Iron, or Fe, has 26 electrons, with two electrons in the outer valence shell. Iron is a transition metal and is both lustrous and easy to work with. Iron is also prone to rust, especially in damp environments. Iron is a ferrous metal, meaning that it can be magnetized.

Answer:

Iron has a valency of 2+

Explanation:

The atomic number for Fe is 26, so that makes the electron configuration 2.8.8.8.2 so if you take the no. of electron it will be 2, so it will have to loose the two electrons in order to fill it's outermost electrons.

So it will develop a valency - 2+

Remember as you loose an electron the valency will be a positive but if you gain an electron the charge will be a negative

Draw a Lewis structure for C2H3Cl . Include all hydrogen atoms and show all unshared electron pairs. None of the atoms bears a f
Korvikt [17]

Answer:

See attached picture.

Explanation:

Hello!

In this case, since C2H3Cl is an organic compound we need a central C-C parent chain to which the three hydrogen atoms and one chlorine atom provides the electrons to get all the octets except for H as given on the statement.

In such a way, on the attached picture you can find the required Lewis dot structure without formal charges and with all the unshared electron pairs, considering there is a double bond binding the central carbon atoms in order to compete their octets.

Best regards!
