Because Na has one too many electron to be stable, while Mg has 2. once they loose those electrons, they will be come ion. loosing one electron will give the ion a 1+ charge, and loosing 2 will create a 2+ charge
The Dominant trait or allele masks the recessive because it is dominant. an easy way to remember this is how the lead wolf (dominant alleles) shows it's dominance over the rest of the pack (the recessive alleles)
<h2>The required "option is d)".</h2>
Explanation:
- Remineralization of enamel is a natural process and is of the same color.
- The saliva contains calcium, phosphate, and fluoride which helps in the neutralisation of acids present in food.
- Remineralization helps in improving the strength and functioning of the tooth by replacing calcium ions and flouride ions which were removed by demineralization.
- It helps in prevention of cavity formation in teeth and strengthens the teeth by replacing loss of calcium ions, phosphate ions, and fluoride by fluorapatite crystals that are more resistant to acids.
- Hence, the remineralized crystal is more resistant to acids.
Answer:
The element is Na
Explanation:
Ionization energy is the energy needed to release the last electron from an atom in its ground state to the gaseous state. It is a periodic property that increases as we go through the periods of the periodic table, but decreases if we move in groups. Sodium has thr ionic radius (another periodic property) that is too large, making it easier to release the electron away, since it is too far from the nucleus.
