Answer:
Na₂O is the formula for the ionic compound "sodium oxide".
It has 2 sodium atoms and 1 oxygen atom.
The number of atoms for an element are written as a subscript after the element. "1" subscripts are not written.
The names of the elements are found on the periodic table.
The crude oil is heated in a process of fractional distillation (note: you can research this online if you require more detail) and this process causes different hydrocarbons to condense at different heights up the distillation column. They will therefore run down the side of the column and into different areas depending on their boiling point.
Answer:
Its 19.
Explanation:
K (potassium) has 19 electron according to the atomic number in the periodic table. The atomic number tells you the number of protons and electrons.
The normal atomic orbitals are joined mathematically during the process of hybridization to create new atomic orbitals known as hybrid orbitals. Even if hybrid orbitals are not identical to regular atomic orbitals.
<h3>What are atomic orbitals?</h3>
Atomic theory & quantum mechanics use the mathematical concept of a "atomic orbital" to describe the location and wavelike behavior of an electron within an atom. Each of those orbitals can contain a maximum of electron pairs, each with a unique spin quantum number s.
<h3>How are atomic orbitals calculated?</h3>
Within every of an atom's shells, various orbital combinations can be found. The n=1 shell has just s orbitals; the n=2 shell contains s and p orbitals; the n=3 shell contains s, p, and d orbitals; and the n=4 up shells include all four types of orbitals.
