Answer:

The symbol of the ion is A^-

Explanation:

Let A be the symbol of the element.

Proton = 17

Electron = 18

Neutron = 20

Since the element has more electrons than protons, it means it has gain electrons.

From the question given,

The difference between the electron and proton = 18 — 17 = 1

So, the element has gain 1 electron.

Therefore the symbol of the ion is A^-

Answer:

Prop-1-yn-1-ide

Explanation:

In this case, we will have an acidic hydrogen upon the left carbon in the alkyne. In the presence of a base, we can remove this hydrogen. In this reaction the base will be $NH_2^-$ . The amidure ion will remove the hydrogen of the alkyne to produce a carboanion. (See figure)

What percentage of the electromagnetic spectrum is visible light

12345 [234]

Well - it depends on where you start and where you finish on the electromagnetic spectrum. But by most estimates, we're can see about 0.0035% of the electromagnetic spectrum (that includes gamma rays, radio waves, x-rays, infrared, ultraviolet, microwaves, etc.).

Hope this helps!
