Answer:

A tritium is produced.

Explanation:

Combining two additional neutrons to the nucleus of the hydrogen atom makes it a tritium, Hydrogen-3.

   neutron is designated  ¹₀n; this shows a mass number of 1 and no atomic number

  Hydrogen-1 is designated as ₁¹H; a mass number of 1 and atomic number of 1. This particle is actually more like a proton.

        Combining both:

                  ₁¹H + 2¹₀n → ³₁H

This is a nuclear reaction and in balancing such reaction equation, mass numbers and atomic numbers must be conserved.

The elements in which electrons are progressively filled in 4f-orbital are called.
Y_Kistochka [10]

The elements in which electrons are progressively filled in 4f-orbital are called lanthanoids.

There are 15 metallic chemical elements called lanthanoids.

Those elements are with atomic numbers from 57 to 71.

Lanthanoids belong to f-block elements because of the filling of the 4f-orbitals.

One of the lanthanoids, lutetium (chemical symbol Lu) has 14 electrons if 4f orbitals.

Electron configuration of lutetium: [Xe] 4f14 5d1 6s2

f-orbitals are similar to the d orbital, but cut in half (eight lobes instead of four).

Lanthanoids are used not as materials in catalysts, alloys, lasers and cathode-ray tubes.

Rank these real gases according to how closely they resemble an ideal gas. CO, N2, Ne, He, NH3
Gemiola [76]

He is the closest. Then:

Ne, N2, CO, NH3.

NH3 is the least closest to ideal.

Phosphorus has three electrons in its 3p sublevel and sulfur has four. Phosphorus should have the lower ionization energy but it
Nadya [2.5K]

Answer:

B

Explanation:

First of all it is important to know that a half filled orbital is particularly stable. In phosphorus all the electrons occur singly in the 3p sublevel minimizing inter electronic repulsion hence it is more difficult to remove an electron from this energetically stable arrangement. In sulphur, electrons are paired in one of the 3p orbitals thereby lowering the energy of that level due to instability caused by interelectronic repulsion between two electrons in the same orbital.
