The closeness of a measure value to the accepted value is called its accuracy.

Explanation:

There are two things in physics you have to be conversant with. That's precision and accuracy. Precision is the closeness of a set of values obtained in identical measurements. e.g titre values: 15.10, 15.05, 14.95, 15.00 (cm3). The values are so close to each other and are said to be precise. But measurements of 5.25g, 5.30g, 4.90g, 6.00g are not precise.

Accuracy is the closeness of a single value to the true value. If the measure value is very close to the true value, we say that the measurement is accurate. A measurement can be precise and not accurate and it might be accurate and precise at the same time.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

can you list the answers so i can answer
