A compound is chemically bonded together atoms and a mixture is two substances combined, i think its D
<span>All crystalline solids contain vacancies. In fact, vacancies is one of the properties of a crystalline solids, for their presences is what creates their random (entropic) design. Furthermore, it is near impossible to create any solid matter that does not contain vacancies/defects. Vacancies can be created by the absence of an atom during matter creation; thermal vibrations can create such a defect as well.</span>
Hybrid Orbitals: are used to describe the orbitals in covalently bonded atoms sp,sp2,sp3
You can find the hybridization by adding the number of bonded atoms and the number of lone pairs.
For example in BF3. The central atom (B) is bonded to three atoms. So the hybridization is sp2
In NH3, the central atom (N) is bonded to three atoms and has one lone pair. The hybridization is sp3
The answer is
. A magnesium atom has 12 protons and an arrangement of [2, 8, 2]. When you lose two electrons, arrangement becomes [2,8] and the atom becomes a positively charged ion
