Question

5 electrons, 5 protons and 6 neutrons. Given data determines the name of the element which is __________________ and its atomic mass is ____________.

1

Boron, 11

2

Carbon, 16

3

Boron, 12

4

Helium, 02​

Answer 1

Answer:

Boron ,11

Explanation:

Atomic mass = No of protons + No of neutrons =5+6=11

Atomic Number 5 is boron

Answer 2

$\huge\fcolorbox {black}{pink}{Required answer}$

Given 5 electrons

5 protons

6 neutrons

Then The atomic number of boron is 5 No .of protons also 5

Neutrons=Mass number-Atomic number

☆Atomic number of boron 5

☆Mass number of boron 11

So neutrons = 11-5 =6

Given that also same

So the Required answer is Boron option a
