Complete Question
The complete Question is shown on the first and second uploaded image
Answer:
The underlined words are the answers
Part A
Moving from boron to carbon, the intensity of the bulb <u>Increases</u> because Z increases from <u>5</u> to <u>6</u> , The thickness of the frosting <u>stays the same </u> because the core electron configuration is the same for both atoms
Part B
Moving from boron to aluminum the intensity of the bulb <u>Increases</u> because Z increases from <u>5</u> to <u>13</u> . The thickness of the frosting also <u>increases</u> because Al has the core configuration of <u>Ne</u>, while B has the core configuration of <u>He</u>
Explanation:
Here Z denotes the atomic number
Ne denoted the element called Neon and its electronic configuration is

He denoted the element called Helium and its electronic configuration is

B denoted the element called Boron and its electronic configuration is

Looking at its electronic configuration we can see that the core is He
I,e ![[He]\ 2s^2 2p^1](https://tex.z-dn.net/?f=%5BHe%5D%5C%202s%5E2%202p%5E1)
Al denoted the element called Aluminium and its electronic configuration is

Looking at its electronic configuration we can see that the core is Ne
I,e ![[Ne]\ 3s^2 \ 3p^1](https://tex.z-dn.net/?f=%5BNe%5D%5C%203s%5E2%20%5C%203p%5E1)
I think, C. An ore. Sorry if wrong
The second answer choice is not true (ozone is concentrated in the stratosphere, not the exosphere)
