An electric field is created by particles that have a charge. These can be either positively or negatively charged. The direction of the field is away from positive charges and towards negative charges.
An electric field is generally created by particles that have a charge. These particles can either be positively or negatively charged. The direction of the electric field is always directed away from positively charged particles and towards negatively charged particles. The magnitude (or strength) of the electric field at a point in space is defined as the force that a positive test charge would experience if it was placed at that point divided by the magnitude of the test charge. For example, if we place a positive test charge in the field produced by another positive charge, the test charge will be repelled - illustrating the direction of the electric field. Hence, even though moving charged particles and radioactive particles can create an electric field, the most generalized answer to this question is that an electric field is created by particles that have a charge regardless of their state of motion or radioactivity.

(2) equal to the number of protons gained

(4) less than the number or protons gained
The standard units of measurement are particularly important to scientists because they make the result more accurate and precise.
When the average value of the different measurements is similar to the correct value then the measurement is said to be accurate and the phenomenon is said to be accurate.
When the values of measurement are close to each other then the result is said to be precise and the phenomena are said to be precise and need to do for the better accuracy of results.
Therefore, they make the result more accurate and precise.The standard units of measurement are particularly important to scientists.

Explanation: The standred units of measurments are important to scientists because they are the same measurments that all scientist take to make sure that they all have the correct results.
