Answer:
Halogens
Explanation:
From the given choices, the halogens will have the smallest radius within the same period.
The size of an atom is estimated by the atomic radius. This is taken as half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements or half of the distance between two nuclei in the solid state.
- Across a period in the periodic table, atomic radii decrease progressively from left to right.
- Down a group from top to bottom, atomic radii increase progressively due to the addition of successive shells.
Since halogen is the right most group from the choices given, it will have the smallest radius.
Water forms a covalent bond and oil forms a noncovalent bond
Answer: Slowly move at least 3 m away from the side mirror. Observe your image as you ... Compare the images formed in different mirrors. ... but if i stand 3m away, even though there is no light, it reflects the other material it can ... is transparent so you cannot see yourself much in the mirror, that is my observation.
Explanation:
Wireless devices, wi-fi routers, granite countertops, microwaves, cigarettes (if you smoke in your house), older box-shaped tv’s, antiques (furniture, jewelry, silverware), smoke detectors ( some use small amounts of radioactive isotope, americium-241 to alert you when there’s smoke in the air, light bulbs, computer screens, electric blankets, garage door openers. Hope it helps.
