Plse help i need so much help on thes questions i am SO confused
10. What is stucturally diffrent between an atom and an ion?
13. If prontons and neutrons have the same mass wat is the approximate mass of apronton and nuetronin atomic mass units (amu)?
16. What is the charge on every atom? Why is this a charge? How do you determine the charge on a ion?
Plse help and thx a million
10. What is stucturally diffrent between an atom and an ion? Atoms lose or gain electrons to become positive or negative ions.
13. If prontons and neutrons have the same mass what is the approximate mass of apronton and nuetronin atomic mass units (amu)? Protons (notice the correct spelling) and neutrons, on the relative scale, have a mass of 1
16. What is the charge on every atom? Why is this a charge? How do you determine the charge on a ion? The charge on all atoms is zero because atoms have equal number of protons (with a positive charge) and neutrons (with a negative charge). The charge of an ion is determined by counting the excess of electrons or protons. An excess of 1 proton is +1 charge, an excess of 2 protons is +2 charge, an excess of 2 electrons is -2 charge, etc.
Thank you sooo muchh!!!!!!! :) :) :) :)

I'd be happy to help you with these questions! Let's go through them one by one.
10. The main structural difference between an atom and an ion is the presence of an electrical charge. An atom is electrically neutral, meaning it has an equal number of protons and electrons, which balance each other out. On the other hand, an ion is an atom that has gained or lost electrons, resulting in an overall positive or negative charge. So, the structural difference between an atom and an ion is the presence or absence of extra electrons.
To better understand this difference, you can visualize an atom as a tiny solar system, with protons and neutrons in the nucleus (center) and electrons orbiting the nucleus in energy levels. In an atom, the number of electrons equals the number of protons.
13. Protons and neutrons have almost the same mass. The approximate mass of a proton and a neutron in atomic mass units (amu) is around 1 amu. Keep in mind that an atomic mass unit is a unit of mass used in chemistry and physics to express atomic and molecular weights. So, both protons and neutrons are roughly 1 atomic mass unit.
16. Every atom is neutrally charged because the number of protons (positively charged particles) in the nucleus is equal to the number of electrons (negatively charged particles) around the nucleus. As a result, the positive and negative charges balance each other out, creating a neutral charge.
However, when an atom loses or gains electrons, it becomes an ion. The charge on an ion is determined by the number of electrons gained (negative charge) or lost (positive charge). For example, if an atom loses one electron, it becomes positively charged and is denoted as a cation. On the other hand, if an atom gains one electron, it becomes negatively charged and is denoted as an anion.
To determine the charge on an ion, you need to know the number of protons (which doesn't change) and the number of gained or lost electrons. The overall charge can be calculated by subtracting the number of electrons gained from the number of protons. For instance, if an atom has 10 protons and loses 2 electrons, the resulting ion would have a charge of +8 (10 protons - 2 electrons).
I hope this explanation helps! If you have any more questions, feel free to ask.
