Answer: Precision is a measure of how close a series of measurements are to one another. Precise measurements are highly reproducible, even if the measurements are not near the correct value. Darts thrown at a dartboard are helpful in illustrating accuracy and precision
Explanation: a if this wrong u fault u gave no detail
Answer:
1 mole of CO2 contains 6.022 x 10^23 molecules
therefore, 1.5 mole should contain 6.022 x 10^23 / 1.5 4.014 x 10^23 molecul
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.
