How many electrons are in a nickel Ni ion that has an atomic number of 28 and a positive charge of 2?

How many electrons are in a nickel Ni ion that has an atomic number of 28 and a positive charge of 2?

Nickel Ni28 has 28 electrons. 18 electrons fill up the third electron shell leaving 10 valance electrons. 2 electrons in the 4s and 8 elections in the 3d. When Nickel becomes Ni+2 Nickel has lost 2 electrons leaving the atom with only 8 valance electrons.

How many protons neutrons and electrons are there of nickel has an atomic number of 28 a mass number of 58 and a charge of 2?

Ni-58 has an atomic number of 28 and a mass number of 58. Therefore, Ni-58 will have 28 protons, 28 electrons, and 58-28, or 30, neutrons.In Ni-60 2+ species, the number of protons is same as in neutral Ni-58.

What has the greatest atomic mass?

Oganesson has the highest atomic number and highest atomic mass of all known elements. The radioactive oganesson atom is very unstable, and since 2005, only five (possibly six) atoms of the isotope oganesson-294 have been detected.

Where is nickel found naturally?

Nickel is one of the primary elements of the Earth’s core which is thought to be made mostly of nickel and iron. It is also found in the Earth’s crust where it is about the twenty-second most abundant element. Most nickel that is mined for industrial use is found in ores such as pentlandite, garnierite, and limonite.

Where is nickel mostly found?

Today, most nickel is obtained from the mineral pentlandite (NiS·2FeS). Most of the world’s supply of nickel is mined in the Sudbury region of Ontario, Canada. It is believed that this large deposit of nickel ore is a result of an ancient meteor impact. Nickel is a hard, corrosion resistant metal.
