9.Both fission and fusion are nuclear processes by which atoms are altered to create energy, but what is the difference between the two? Simply put, fission is the division of one atom into two, and fusion is the combination of two lighter atoms into a larger one
10.The electroscope is a fairly simple device comprised of a metal rod with two thin leaves attached to one end. If the electroscope is given a negative charge, the metal leaves will separate from each other. It is this characteristic that makes the electroscope useful as a detection device. A negatively charged electroscope will discharge when ions in the air remove electrons from it, and consequently, a positively charged electroscope will discharge when it takes electrons from the air around it. The rate of discharge of the electroscope is a measure of ions in the air and can be used as a basis of measurement and detection
11. they are bigger and colide with atoms easier
Answer:
The answer to your question is 12
Explanation:
Data
Number of electrons in Phosphorus 3+ ion
Process
1.- The sign of the number after the name indicates if the element has lost or gained electrons.
If the sign is positive the element has lost electrons
If the sign is negative the element has gained electrons.
2.- Phosphorus atomic number is 15, then the number of electrons in Phosphorus 3+ will be 12, in this example, Phosphorus lost 3 electrons.
We did a lab on this.
hydrogen peroxide on a raw liver bubbles up and stinks.
