Question

Write the chemical symbol for three different atoms or atomic cations with 24 electrons

Answer 1

The chemical symbols for three different atoms or atomic cations with 24 electrons are: chromium (Cr), manganese cation (Mn+), and iron cation (Fe2+).

Step-by-step explanation:

To write the chemical symbol for three different atoms or atomic cations with 24 electrons, we look at the periodic table to find elements or ions that have this number of electrons. Neutral chromium (Cr) has 24 electrons because its atomic number is 24, which means it has 24 protons and, when neutral, an equal number of electrons. Manganese (Mn) has an atomic number of 25, so the Mn+ cation, which has lost one electron, also has 24 electrons. Lastly, iron (Fe) has an atomic number of 26, so the Fe2+ cation, which has lost two electrons, has 24 electrons. In these examples, the atomic cations and atoms have adapted their electron count to reach the stable configuration of 24.

Answer 2

First, we write the atom with 24 electrons. Atoms are neutral, so their electrons and protons are equal in number. The element with proton number 24 is chromium.

Next, a manganese atom has 25 electrons, so if it forms a cation with a +1 charge, it will have 24 electrons. Similarly, if an iron atom which normally has 26 electrons forms a +2 charge cation, it also has 24 electrons. The three symbols are:

Cr
Mn⁺¹
Fe⁺²
