Question

What is the net charge of the elements Ni, I and Au on the periodic table?

Answer 1

Hint : To answer this question, we first need to understand what a periodic table is. The periodic table is a tabular arrangement of chemical elements that is ordered by increasing atomic number and grouping elements by repeating qualities. Metals are on the table's left side, while nonmetals are on the right. Groups refer to the columns.

Complete Step By Step Answer:
Net charge: When there are more protons than electrons in an object, the net charge is positive. The net charge on an object is negative if there are more electrons than protons. The object is electrically neutral if the number of protons and electrons is equal.
Ni - Nickel is a chemical element with the atomic number 28 and the symbol Ni. It's a glossy silvery-white metal with a faint golden hue. Nickel is a transition metal that is both hard and ductile.
I – Iodine is a chemical element with atomic number 53 and the symbol I. At ordinary conditions, it exists as a glossy, purplish-black non-metallic solid, which melts to produce a deep violet liquid at 114 degrees Celsius and boils to produce a violet gas at 184 degrees Celsius.
Au - Gold is a chemical element with the symbol Au (from Latin: aurum) and an atomic number of 79, making it one of the higher atomic number elements found in nature. It is a thick, soft, malleable, and ductile metal that is bright, somewhat reddish yellow in its pure form.

Note :
As we know, matter is electrically neutral. Every positive charge has an equal and opposite negative charge. To be sure, elements can form ions when electrons are lost or gained. Non-metals (to the right of the Periodic Table) gain electrons to form anions, while metals lose electrons to make cations.
Some of the ions of the given elements are $N{i^{ + 2}},{I^ - },A{u^ + },A{u^{ + 3}},etc$.
So, elemental nickel, iodine, and gold have ZERO net charges.
