how are the elements in a pair of isotopes the same? how do they differ?
And also if you know anything about the atomic structure phrase apeman i could use some serious help right now i have a test tommoro and i cant remember all the material
Isotopes. They have the same atomic number (same number of protons), a different number of neutrons (mass number is different), and the same number of electrons.
As for the Apeman I never heard of it; however, I googled atomic structure by apeman and it returned this link. Apparently it is a presentation of the periodic table by a talking ape.
Hope this helps.

In a pair of isotopes, the elements are the same because they have the same atomic number, meaning they have the same number of protons in their nucleus. For example, hydrogen-1 and hydrogen-2 are both isotopes of hydrogen because they both have one proton.
However, isotopes differ in their number of neutrons. Neutrons are subatomic particles found in the nucleus of an atom. Isotopes of an element have different numbers of neutrons, which leads to a difference in their atomic mass. For instance, hydrogen-1 has no neutrons, while hydrogen-2 (also known as deuterium) has one neutron.
Isotopes generally have similar chemical properties since they have the same number of electrons, which determines an element's chemical behavior. However, they may exhibit slight variations due to their difference in atomic mass, affecting their physical properties, such as density or boiling point.
Regarding the atomic structure phrase "apeman," it appears to be an acronym used to remember the arrangement of electrons in atomic orbitals. Each letter represents the different types of orbitals in an atom: "a" for s-orbital, "p" for p-orbital, "e" for empty orbital, and "man" for d- and f-orbitals. It helps to remember the order in which electrons fill these orbitals.
Here's a breakdown of electron arrangement using the "apeman" phrase:
1. "a" represents the s-orbital, which can hold up to 2 electrons.
2. "p" represents the three p-orbitals, which can hold a total of 6 electrons (2 in each p-orbital).
3. "e" signifies an empty d-orbital, as d-orbitals are filled after all s- and p-orbitals.
4. "man" indicates the five d-orbitals and seven f-orbitals. These can hold a maximum of 10 electrons in the d-orbitals and up to 14 electrons in the f-orbitals.
Remembering the "apeman" phrase can be a helpful mnemonic device, but it is essential to understand the electron configuration conceptually and practice using the periodic table to determine electron arrangements accurately.
Good luck with your test, and I hope this information helps you prepare!
