A certain element forms an ion with 54 electrons and a charge of +2. Identify the element.
Ba
54 electrons with +2 charge means it must have 56 protons? What is element with atomic number of 56?
Ba
To identify the element, we need to determine the atomic number of the element based on the given information.
First, we know that the ion has a charge of +2. This means that it has lost 2 electrons. The number of electrons in a neutral atom is equal to the atomic number.
Therefore, the atomic number of the element would be 54 + 2 = 56.
To identify the element, we need to refer to the periodic table. The element with an atomic number of 56 is Barium (Ba).
So, the element in question is Barium (Ba).
