Answer:
54
Barium atomic number is 56, this means that it has 56 protons in its nucleus and put it as a period 6 element. an uncharged barium atom would have 56 electron also. However as a group 2 element barium easily loses 2 electron to form the +2 cation. the ions has 56-2=54
Those reactions in which Alkyl Halide reacts with the solvent without the involvement of any acid or base is called as
Solvolysis. In given problem <em>tert</em>-Butyl Bromide is a tertiary Alkyl Halide and we know well that tertiary alkyl halides undergo
SN¹ and
E¹ elimination reaction due to the formation of
stable tertiary carbocation. In given example after the formation of carbocation when Isopropyl act as
nucleophile it will produce
ether and when it acts as a
base it will produce
unsaturated compound. The reaction along with both products is shown below,
Answer:
Mass = Number of neutrons + Atomic number (aka number of protons)
Explanation:
The outer electrons of an element are called the valence electrons. They help make an element stable.
Cesium : 1 valence electron<span>.
Magnesium : 2 valence electrons</span>
I like ELA and Math because it motivates me to draw and sketch, which can help with me and my future plan.
