Question

Write the symbol for an atom or ion with:

a. five electrons, five protons, and six neutrons.

b. five electrons, six protons, and eight neutrons.

Short answer

a. The atom${}^{11}B$.

b. The ion is${}^{14}{C}^{+}$.

Step-by-step solution

Part (a) step 1: Given information

We need to find the the symbol for an atom or ion with five electrons, five protons, and six neutrons.

Part (a) step 2: Explanation

As there are $5$protons the element is Boron (B) so the symbol is${}^{11}B$.

Part (b) step 1: Given information 

We need to find the the symbol for an atom or ion with five electrons, six protons, and eight neutrons.

Part (b) step 2: Explanation

The element is carbon (C) and since it has $1$electron which is less than proton it is an ion. So the symbol is${}^{14}{C}^{+}$.
