To solve an isotope problem, you need to identify the number of protons and neutrons in the atom and determine the mass number by adding them together. For an ion problem, you need to determine whether the ion has gained or lost electrons compared to a neutral atom and then calculate the overall charge by considering the number of protons and electrons.
why electrons didn't fall into the positive nucleus how so many positive charges could be crowded into such a small space in the nucleus how so much energy could be released from an atom
C= 4 x 1 = 4 O= 6 x 3 = 18 ------ 22 - 2 ----- 24* * Because a (-) is adding and (+) is subtracting.. so since this problem is a (-2) then you will add it to the total found.. hope this helps!
for that you should have the knowledge of the electron configuration 2,8,8,18,32,.. meaning first electronic orbit can have at the most two electrons. second orbit can have only 8 electrons and so on.... Now, for example calcium atomic number is 20 . so how will be the electrons placed 2 will go in the first orbit, 8 will go in the second orbit - so till now total is 10 we still have 10 more electrons to arrange. 8 electrons go in the third orbit and last 2 electrons go in the fourth orbit which actually has the capacity to accept total of 18 - now 2 electrons come in the fourth orbit so 18-2=16 . for any element it requires a lot of energy to get 16 electrons from the atom of other element so it will be better to loose 2 electrons for the calcium atom. Ca +2 means it has 2 electrons to loose . try this with different element and if you have any problem I will help you

Lightbulbs flicker when there is a problem with the electrical connection or the bulb itself. This can be caused by a loose connection, a faulty bulb, or fluctuations in the electrical supply.
The lights are blinking because there may be a problem with the electrical connection or a malfunction in the lighting system.
The light is flickering because there may be a loose connection in the electrical wiring or a problem with the light bulb itself.
The flickering of light in a house is typically caused by a loose or faulty electrical connection, a problem with the light bulb itself, or fluctuations in the electrical supply.
In my experience most problems are either a bad ground connection, or a short circuit somewhere. Shorting will probably be due to a chaffed wire, or loose connection.
The lights are blinking on and off because there may be an issue with the electrical connection or a problem with the light bulb itself.
The fluorescent lights may not be working due to a faulty bulb, a problem with the ballast, or issues with the electrical connection.
Your fluorescent light may not be working due to a faulty bulb, a problem with the ballast, or issues with the electrical connection.
The red light on the electrical outlet is blinking to indicate that there may be an issue with the electrical connection or that there is a problem with the outlet itself. It is a warning signal to alert you to investigate and potentially address the issue to prevent any electrical hazards.
I have found that to fix an electrical problem it is best to break it down into smaller pieces. Example: Do I have power between A & B. Yes, OK Do I have power between B & C. Yes, OK Do I have power between C & D. No, Why? Found bad connection - problem fixed.
