A student reads that bromine (Br) tends to gain one electron in chemical interactions. Which BEST describes a region of the periodic table where all elements tend to share this property?
What is group 17? Where is it?

When I was in college, the Br-containing group was called VIIA. That was a long time ago.
Ah, the wondrous world of chemical interactions! Let me put on my clown nose and humor you with an answer. Picture this - imagine a region on the periodic table where all elements gather and have a little electron-sharing party. Let's call it the "Electron Sharing Shindig Zone."
In this Electron Sharing Shindig Zone, elements are friendly and always ready to gain an electron, just like our friend bromine (Br). It turns out, this place is known as Group 17, or the Halogens. Yes, those fluorine (F), chlorine (Cl), and iodine (I) fellas love to snatch up an extra electron too.
So, if you find yourself invited to the Electron Sharing Shindig Zone, be prepared to witness these halogens showing off their electron-gaining moves. It's the hottest spot for electron shenanigans!
The property described in the question refers to the tendency of an element to gain one electron in chemical interactions, which is known as "electron affinity." To find a region of the periodic table where all elements tend to share this property, we need to locate the elements with a higher tendency to gain an electron.
One way to determine this is by examining the periodic trends. Electron affinity generally increases across a period from left to right and decreases down a group from top to bottom. Hence, elements at the far right side of a period or towards the top of a group might have a higher tendency to gain an electron.
In particular, Group 17 of the periodic table, also known as the Halogens, tends to exhibit a high electron affinity. The elements in this group include fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). Therefore, the region of the periodic table where all elements tend to share the property of gaining one electron in chemical interactions is Group 17.
