Answer:

(a). Number of protons in a chlorine atom = 17

(b). Atomic number of sodium = 11

Step-by-step explanation:

Let the number of protons in a sodium atom = <em>x</em>

Then, the number of protons in a chlorine atom =<em> x</em> + 6

Now, it is given that the atomic number of an element is equal to the number of protons per atom.

So, atomic number of sodium (Na) = <em>x</em>

Atomic number of chlorine (Cl) = <em>x</em> + 6

It is given that the atomic number of chlorine is 5 less than twice the atomic number of sodium.

∴ atomic number of chlorine (Cl) = 2 × atomic number of sodium (Na) - 5

⇒ <em>x</em> + 6 = 2<em>x</em> - 5

⇒ <em>x </em>- 2<em>x</em> = -5 - 6

⇒ -<em>x</em> = -11

Cancelling the minus sign from both sides, we get

<em>x</em> = 11

(a). Number of protons in a chlorine atom = <em>x</em> + 6

                                                                     = 11 + 6      (∵ <em>x</em> = 11)

                                                                     = 17

(b). Atomic number of sodium = <em>x</em> = 11
