Answer:
D
Explanation:
Just look at the groups and their tendencies. Or look at their electron configurations. You will notice that calcium has 2 valence electrons and bromine has 7 valence electrons.
Halogens have the most valence electrons possible without completing a shell (8 would be needed for that)
The answer is glyceride, hope I helped
Explanation:
Hey there!!
We generally use s,p,d,f formula.
So, let's do with it.
1.Neon
Atomic no. = 10
So, Its electronic configuration is;
2.Zinc.
Atomic no. = 30
So, it's electronic configuration is;
3. Tungsten.
Atomic no. = 74.
So, it's electronic configuration is;
4. Magnesium.
Atomic no. = 12
So, the electronic configuration is ;

Answer:
C
Explanation:
The question asks to know what happens when an electron moves from a higher energy level to a lower energy level.
Firstly, it is important to note that when an electron moves from a lower energy level to a higher energy level, energy is absorbed by the atom. Conversely, when an electron moves from a region of higher energy to a region of lower energy, energy is released by the atom.
Thus we can say that the movement of an electron from a region of higher energy to a region of lower energy can result in the emission of a photon of light as energy is released by the atom
