Low electron affinity and large atomic radius
Metallic character decreases across a period (from left to right) and increases down a group.
Electron affinity increases from left to right within a period. This is caused by the decrease in atomic radius. Electron affinity decreases from top to bottom within a group. This is caused by the increase in atomic radius.

Explanation:
The most common injuries in a chemistry lab is making a fire, heat burns, chemical burns, cuts and scrapes, contamination, inhalation, and spills and breaks.
1.) You can prevent making a fire by making sure you close and seal flammable materials.
2.) You can prevent heat burns by teaching the students how to properly use tongs,water baths, and other cooling equipment.
3.) You can prevent chemical burns by treating the chemicals with caution, measure carefully, and use the approved containers.
4.) You can prevent cuts and scrapes by telling the students how to use the blades safely, and also when they are disposing broken or sharp items they should know how to wrap them up so no one else will get hurt.
5.) You can prevent contamination by washing your hands, protect their clothing and skin with a lab coat or a lab apron, gloves and glasses, and cleaning your area where the germs of the chemicals were so no one will become.
6.) You can prevent inhalation by opening up windows, using ventilation fans, and using an equipment that measures the amount of gas emission in a room.
7.) Finally, you can prevent spills and breaks by telling the students what will happen if anything spills, and tell them to clean up.
