Neutrons are uncharged
proton (+4) + electrons (-5)= -1
Answer:
2.25?
Explanation:
Im a 7th grade and have no idea but I think the pressure Will be 2.25 ATM because 3 which is the volume after minus the 0.75 which was the first volume but I dont really know srry
Answer:
Explanation:
The first step is:
Second step is:
Multiplying second step by 2, and adding both the steps, we get that:
Cancelling common species, we get that:
Answer:
1. 17 protons / 10 neutrons
2. Scandium
3. Negative
Explanation:
1. The bottom number is the same as the atomic number on top of the abbreviation. To find the # of neutrons, subtract the mass number with the number of protons
2. The bottom number (21) is the number of protons AND the atomic number (the a.n & # of pro. are always going to be the same)
3. Always think about this: if you add electrons, you take away charge - if you take away electrons, you add charge
*Idek if these were the correct correct answers but I tried my best*
Answer: yes
Explanation: Radioactive (or nuclear) waste is a byproduct from nuclear reactors, fuel processing plants, hospitals and research facilities. Radioactive waste is also generated while decommissioning and dismantling nuclear reactors and other nuclear facilities. There are two broad classifications: high-level or low-level waste.
