Answer: Atomic mass of the element is 56.
Given: A tripositive ion has 23 electrons and 30 neutrons.
To Find: Atomic mass of the element.
Explanation:
Step 1: An atom or molecule with a net electrical charge is known as an ion.
Conventionally, the charge of an electron is thought to be negative; this charge is equal to and opposite to the charge of a proton, which is thought to be positive. Because the total number of electrons in an ion is more than the total number of protons, the net charge of an ion is not zero.
Step 2: In contrast to an anion, which is negatively charged but has more electrons than protons, a cation is an ion that is positively charged but has fewer electrons than protons.
Electrostatic force causes opposite electric charges to be drawn towards one another, causing cations and anions to attract one another and easily form ionic compounds.
Step 3: An element become an ion when it loses or gains some electrons. Here we have a tri-positive ion which means there is a deficiency of three electrons in the atom of element.
As we know that number of electrons or protons = Mass number - number of neutrons.
Mass number = number of proton + number of neutrons
Here, number of proton = number of electrons = 23+3 = 26
Mass number = 26+30 = 56
Hence, atomic mass of the element is 56.
