Answer;
-Copper (Cu)
Explanation;
-While all metals can conduct electricity, certain metals are more commonly used due to being highly conductive. The most common example is Copper. It is highly conductive which is why it is has been used in electrical wiring.
-Copper is used for electrical wiring because it is a good conductor of electricity. Metal particles are held together by strong metallic bonds, which is why they have high melting and boiling points. The free electrons in metals can move through the metal, allowing metals to conduct electricity.
Based on the aforementioned measurements, the following applies;
- The measurements are not accurate
- The measurements are precise
<h3>What is accuracy and precision?</h3>
Accuracy is the exact conformity to truth, or to a rule or model or the degree of conformity of a measure to a true or standard value.
Precision is the ability of a measurement to be reproduced consistently or the closeness of measured values.
According to this question, the following measurements were made to determine the density of a material whose value was 3.75 g/mL
- Trial #1 - 4.75 g/mL
- Trial #2 - 4.76 g/mL
- Trial #3 - 4.74 g/mL
Based on the above measurements, the following applies:
- The measurements are not accurate because they are not close to the value of the handbook
- The trial measurements are precise because they are close to one another.

Answer:
Superscript 11 subscript 6 upper C right arrow superscript 11 subscript 5 upper B plus superscript 0 subscript plus 1 e.
Explanation:
Beta decay:
Beta radiations are result from the beta decay in which electron is ejected. The neutron inside of the nucleus converted into the proton an thus emit the electron which is called β particle. In beta positive decay proton is converted into neutron and positron, thus the atomic number is decreased by one.
¹¹₆C → ¹¹₅B + ⁰₊₁e
In beta minus decay the one electron is ejected and neutron is converted into proton.
¹⁴₆C → ¹⁴₇N + ⁰₋₁e
Properties of beta radiations:
The mass of beta particle is smaller than the alpha particles.
They can travel in air in few meter distance.
These radiations can penetrate into the human skin.
The sheet of aluminium is used to block the beta radiation
