I don't have any actual venting so the things that need to be moved are the electrical connection and the hanging brackets (and repairs to the ceiling.)

She means that it is a recirculating hood, I think.

The range is a 30 inch wide 24 in deep induction. The burners are set a bit back from the front of the range. The hood is a 36 wide by 24 deep, 760 cfm. This is a condo building with NO option for any ducted exhaust hood so I know that this hood is actually just to meet code and for looks. It is just recirculating. We haven't installed it yet but I had planned on about 33 inches from the top of the range. Behind the range is a 15 inch wide countertop as part of the island so the 7 inches the hood is set back from the front of the range will push it 7 inches over the counter.

Thanks for your questions and helping me to think this through. I'd appreciate all ideas, concerns, and solutions.

If its a recirculating hood, I wouldn't bother moving it. (Though your husband is wrong.)

As I've written many times, that style of hood fails to capture correctly due to the plume's ability to slide out the middle. Also the structure holding that minimal screen filter also blocks the plumes from rising directly to where they can be pulled in and contained. Rising cooking plumes have momentum and tend to reflect off of hard surfaces. Either the surfaces have to be angled to reflect toward the filter, or the airflow near the surfaces has to entrain the plume and direct it toward the filter.

I don't think 760 CFM can be pulled through that small screen with any blower that fits in that "duct" section (screaming mimi aerospace blowers excluded), not to mention also pushing air through the charcoal filtering that I hope is next in line. Maybe the blower is rated at 760 air flow rate when hanging in free air (zero static pressure), but I'd be surprised if more than 300 CFM is moved through that device.

This only matters if serious cooking is intended that generates greasy and/or odoriferous plumes. For light duty (boiling eggs, making rice, even simmering bacon, this hood may suffice.

The image one should have is that there is a pan on an induction hob generating steam and/or grease particulates with some upward velocity -- possibly 2 ft/s for induction without grilling. This plume is also expanding as it rises. There may be drafts that can be similar in velocity if people are walking around, or the house heating is blown air, or an a/c is directed toward the hood. All of these conspire to interfere with capture and containment of the plumes. On top of that, hood filtering is normally not designed to filter everything, just the grease particulates that would otherwise condense on the ducts. The rest is normally expelled outside. With recirculating hoods, multiple filtering layers may be needed to keep the greasy fine particulates from returning to the room and coating the walls, ceiling, furniture, drapes, cat, etc. The charcoal may, if deep enough, deal with odor.

The Vent-a-Hood ARS reportedly achieves these goals with reasonable effect at significant cost. If your cooking becomes enthusiastic, and this system fails to meet your filtering goals, you may want to start looking for an upgrade. There may also be a Broan recirculating filtered hood, but I haven't looked into it.

As for your present situation, I would bias the hood position to optimize collection of all, front, or rear hobs depending on your intended cooking style.

Can you take a picture?

I would want this centred over the range, but I also would have wanted the range centred in the island. If it couldn't be centred then I would have done it completely off centre and not done an overhead fan and done one that pops up and blows. My mom has this and it works great.

Yes, I didn't actually think it was necessary to tell my husband "the range hood should be centered over the range" but I was wrong, lol. The range is centered on the width of the island, flanked by 24 in wide cabinets and the hood will be centered in that dimension but the front to back will be centered on the 40 inch deep island instead of the 25 in deep range. I could live and actually like a couple of inches set back but 7 inches! Given that it really doesn't DO anything as it is recirculating I hate to spend the extra money to have it redone but I don't want it to look stupid either. I keep wondering if hanging it up to 36 inches over the range would help with the look (but it makes the use as a hood worse) or maybe down to 30 inches off the range. I'm not good at visualizing the design features (but I can measure which apparently my husband can not even though he is an engineer.) Unfortunately, I can't take a picture as I'm not there (I left my husband finishing things up while I'm out of town taking care of my dad. Who knows what else will go wrong....)

I did consider the undermount exhaust but the extra space required and cost didn't seem worthwhile since it too would have just been a recirculating fan due to the condo limitations.

@kaseki thanks for all your info. Luckily I'm not a professional cook or even a good amateur so for my kitchen so this hood will probably be fine and may even be better placed by being set back a bit from the front of the range and more over the burners. The A/C vents blow away from the island so hopefully so may even help push the air toward the hood.

Consumer grade recirculating hoods are of minimal or zero value anyway so I wouldn't worry about the placement being off by 7". I don't think having it perfectly over the range would make any difference. If it were a proper ducted hood then I would say to move it.

Update on my hood: I convinced everyone that it had to be moved to over the range. ( me on repeat: "What about 'range hood' led you to believe it shouldn't be over the range?") But they were going to hang it up in the 'wrong' location just to get it out of the way until I could be back on site to supervise the new install. When they went to put it up they discovered that it needed a different mounting situation and couldn't be installed as currently configured. (even though I left everyone the install instructions in the box, in the notebook, and on-line.) So..... everything will be ripped out and moved and installed correctly. All's well that ends well.

Thanks for the update.
