Chromium's atomic number is 24. A neutral atom of chromium would thus have 24 protons and 24 electrons. Since we're dealing with Cr3+, though, we need to subtract 3 electrons from this number, giving us 21.
Au (gold) has a total of 79 electrons, making it the species with the greatest number of electrons among the options provided.
There are 5 electrons in the d orbital of an Os3+ ion.
3 electrons total. electrons is the number on the top right corner with the plus sign indicating that electrons are positive.
26. Nickel has an atomic number of 28, which means that in a normal state, it would have 28 electrons. Ni+2 means that it oxidized by losing two electrons and would thus have only 26 remaining.
The atomic number represents the number of protons in an atom's nucleus, which is also equal to the number of electrons in a neutral atom. Core electrons are those that are closest to the nucleus and are not involved in chemical bonding. The number of core electrons in an atom is equal to the difference between the atomic number and the number of valence electrons.
The Mg2 plus cation has 10 electrons.
Au (gold) has a total of 79 electrons, making it the species with the greatest number of electrons among the options provided.
There are 5 electrons in the d orbital of an Os3+ ion.
Na+ will be a sodium atom that has lost an electron. Normally in atoms the amount of protons and electrons are equal, when you see a plus or minus charge on an atom its due to the loss or gain of electrons.
3 electrons total. electrons is the number on the top right corner with the plus sign indicating that electrons are positive.

An Al3+ ion has 13 protons, making it aluminum, and has lost 3 electrons. Since the number of electrons in a neutral aluminum atom is 13, the Al3+ ion has 10 electrons in total.
This describes an ionic compound with an 8:3 ratio of electrons to cations. The cation has a charge of +3, meaning it has lost 3 electrons. The total number of electrons in the compound is 80.
Argon has 18 core electrons. This is because the atomic number of argon is 18, and the number of core electrons is equal to the number of electrons in the nearest noble gas configuration, which in this case is neon (10 core electrons), plus the number of electrons in the next energy level, which is 8 for argon.
The number of electrons is 10.
Pb which is neutral has 82 electrons. Thus, if it has a 4+ charge, then it has 78 electrons.
