What is the oxidation state of each element in febr2?

<span>To determine the oxidation state of a metal, like Fe (Iron) or anything else really, you generally won't know. But look at a periodic table and you'll see that most metals fall into the sort of "valley" section, and this part of the periodic table is called the "d-block" and it has 10 columns. These guys in the d-block of the periodic table have a special way of filling their orbitals, but everything on the left and right are a little simpler to understand. So we see that Br (Bromine) is one of the easier ones to find the oxidation state of, since it's on the right part of the periodic table (where there are 6 columns) and we know that they follow the octet rule, and since bromine is a halogen (That just means it's in the second to last column, which is next to the noble gasses) and things at the top right of the periodic table are highly electronegative, so they'll tend to gain another electron to have a complete octet to fill its orbitals and have a negative charge. Since it only had to gain one to have a complete octet, it's charge is now -1. We can now look at FeBr2 and see that overall the charge is 0. But it has two bromines which each have a charge of -1, so we see that we can set up a little algebra equation: (Charge of Iron) + (Charge of Bromines)=(Total Charge) So, we have: (Charge of Iron) + 2 (-1)=0 So then we can see that Iron is a +2 oxidation state, Iron (II) Bromide.

An element from the periodic table is shown below. What can you determine about the number of protons, neutrons, and electrons o
Musya8 [376]

Answer:

They are all the same = 8

Explanation:

Since the symbol of that atom is not give, we can infer from the given number the nature and kind of element we are dealing with.

The number 15.999 rounded up to 16 is the atomic weight of the atom also called the mass number.

Although not peculiar enough, we are certain that this atom is Oxygen.

 On the periodic table, elements are arranged based on their atomic numbers.

    Atomic number of oxygen = 8 = number of protons

For every neutral atom on the periodic table, the number of protons and electrons are the same

Atomic number of oxygen = number of protons = number of electrons = 8

 Number of neutrons = Mass number - atomic number = 16 - 8 = 8
