Given :
An atom Iodine.
To Find :
How many electrons will an iodine atom donate or accept, based on its number of valence electrons :
A.donate seven electrons
B.accept one electron
C.donate one electron
D.accept seven electrons
Solution :
We know, valence electron in Iodine is 7 electrons.
So, it is easy for iodine to accept 1 electron rather than giving all 7 electrons to another element.
Therefore, Iodine will accept one electron ( Option B.).
Hence, this is the required solution.
Answer:
what you are putting on the concrete and how thick the concrete is.
Explanation:
If you want to but a house on a slab of concrete for a base, you will probably need a little more than you would for a sidewalk. If it is thicker, you will be able to hold more on it than you would if you spread it out thinly.
<h3>
Answer:</h3>
All atoms of the same element have the same number of protons
<h3>
Explanation:</h3>
- Atoms are the smallest particles of elements that can take part in a chemical reaction.
- Atoms of an element have the same number of protons but may have a different number of electrons or neutrons.
- Atoms of the same element with different neutrons are called isotopes.
- An element may have two or more isotopes. For example, oxygen isotopes; oxygen-16, oxygen-17 and oxygen-18.
- Atoms may have a different number of electrons when they lose or gain an electron(s) to attain a stable configuration.
When you are dealing with mole calculations, whatever you do to one side of the equation you must also do to the other. .5Fe is 1/8th of 4Fe, so in order to determine what it will yield you must divide the given amount of Fe2O3 and divide THAT by 1/8th, leaving you with .25 mol of Fe2O3.
