Answer:
2s² 2p⁵
There are seven valance electrons in fluorine.
Explanation:
The elements of group 17 are called halogens. These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. Halogens are very reactive these elements can not be found free in nature. Their chemical properties are resemble greatly with each other.
Properties of fluorine:
1. it is yellow in color.
2. it is flammable gas.
3. it is highly corrosive.
4. fluorine has pungent smell.
5. its reactions with all other elements are very vigorous except neon, oxygen, krypton and helium.
Electronic configuration of fluorine:
F₉ = 1s² 2s² 2p⁵
Valance electrons in fluorine are 2s² 2p⁵.
Valance Orbital configuration:
2s² 2p⁵
There are seven valance electrons in fluorine.
Answer:
Explanation:
One mole of Fe(NO3)3, or iron(III) nitrate, has three moles of nitrate molecules, which have three moles of oxygen atoms each. We can show this mathematically:
1 mole Fe(NO3)3 * (3 moles NO3)/(1 mole Fe(NO3)3) = 3 moles NO3
3 moles NO3 * (3 moles Oxygen)/(1 mole NO3) = 9 moles Oxygen
9 moles of Oxygen in one mole Fe(NO3)3
Answer:
it is b because its releases heat in to all directions and not b because it staying inside and not releasing anything :)
