Answer:
1. Magnesium and oxygen atoms bond to form an ionic compound; this is evident because one forms a cation and the other an anion. When an ionic compound is formed, one atom "steals" an electron (or electrons) from another. In this case, an oxygen atom (which is pretty electronegative by the way) "steals" 2 electrons from a magnesium atom. The resulting oxygen anion and magnesium cation attract one another to form a bond (more specifically, an ionic one).
2. The oxygen atom needed two sodium atoms to bond because it needs two additional electrons to achieve a stable octet of electrons. 1 sodium atom provides 1 additional electron after it is "stolen" by oxygen, so 2 sodium atoms are needed in total to form the bond.
3. The magnesium atom needed two fluorine atoms to bond because it needs to lose two electrons to achieve a stable configuration/octet of electrons. 1 fluorine atom "steals" one electron, so 2 are needed in total.

Answer:
The chance of having a Child who is a Heterozygote is 50% , The chance of having a child that will completely come down with Alpers syndrome is 0%
Explanation:
Jack has a history of Alpers in his family
Jill has no history
lets assume Jack is a carrier : Ab ( because that is how he could have survived the first 10 lethal years )
Jill : AA
Therefore the probability/chance of Jack and Jill having a child with Alpers ( carrier ) syndrome will be 50 % as shown below
AA * Ab = AA , Ab, AA, Ab
The child produced by Jack and Jill will only be a carrier of the syndrome and not completely affected by the syndrome
Interphase-intermediate phase, DNA replicates
Prophase -coils into chromosomes, chromosomes are made of two chromatids, which join at the centromere at this stage.
Metaphase -Chromosomes line up in the middle of cell on spindles
Anaphase - Chromosomes are pulled apart to opposite ends of the cell by the spindles
Telophase - The cell splits into two cells, and the chromosomes uncoil and begin from the interphase stage again
