What are the dietary requirements for normal bone growth?
Normal bone growth requires a diet rich in calcium, vitamin D, phosphorus, magnesium, and protein. Calcium is important for bone strength, while vitamin D helps with calcium absorption. Phosphorus and magnesium are essential for bone development, and protein is needed for overall bone health.
Why magnesium has lower melting and boiling point than calcium strontium and other members present below magnesium?
Magnesium has a lower melting and boiling point than calcium, strontium, and other members below it in the group because it has a smaller atomic size, lower nuclear charge, and weaker metallic bonding. These factors result in weaker forces of attraction between the magnesium atoms, making it easier to overcome them and melt or boil the metal.
Element M reacts with chlorine to form a compound with the formula MCl2 It is more reactive than magnesium and smaller than barium This element is?
Element M is calcium. It reacts with chlorine to form calcium chloride (CaCl2). Calcium is more reactive than magnesium and smaller than barium on the periodic table.
What element has an ion that is smaller than an ion of calcium?
Fluorine has an ion, specifically the fluoride ion (F⁻), that is smaller than a calcium ion (Ca²⁺). The fluoride ion has a negative charge, which increases its electron cloud size, but its atomic radius is still smaller than that of the calcium ion, which has lost two electrons and has a higher positive charge. Consequently, the increased nuclear charge in Ca²⁺ pulls the remaining electrons closer, resulting in a smaller ionic radius compared to that of F⁻.
Why does the ionic compound calcium fluoride have a different structure from that of calcium chloride?
Calcium fluoride has the fluorite structure where each calxium ion has 8 fluoride ions as near neighbours at the corners of a cube, and eacf fluoride has 4 calcium ions ate the corners of a tetrahedron. Another way of looking at this is that the calcium ions are close packed and the fluroide atoms fill the "tetrahedral holes" In calcium chloride the chloride ion is too large to allow eight coordination and the coordination around the calcium drops to 6, the coordination around the chloride has to drop to 3. This gives CaCl2 a unique structure which is a distorted form of the more regular rutile structure adopted by TiO2.
Which is more reactive Mg or Ca Why?
Calcium is more reactive. In the periodic table, Calcium is directly below Magnesium, which means that a calcium atom is larger than a magnesium atom. This means that the electrostatic attraction between the valence electrons of calcium and the nucleus is weaker than in magnesium(larger distance, smaller force). So, the valence electrons of calcium can easily be lost to form Ca2+ , which translates to Calcium being the more reactive metal.
Why is it harder to remove an electron from Magnesium than it is to remove an electron from Calcium?
Zinc has more electrons in its outer energy level than Calcium. Because of this, itsnucleus is more attracted to this energy level and pulls it more the nucleus in Calcium. Because of this greater attraction it is harder to remove the electron from Zinc.
How does calcium atomic radius compare to magnesiums radius and potassiums radius?
Calcium has a larger atomic radius than magnesium and a smaller atomic radius than potassium. This trend is due to the increase in number of protons and electrons as you move across the period on the periodic table from magnesium to calcium to potassium.
Which are not major minerals out of sodium magnesium calcium iron or zinc?
Out of sodium, magnesium, calcium, iron, and zinc, iron and zinc are not classified as major minerals; they are considered trace minerals. Major minerals, also known as macrominerals, include those required in larger amounts, such as sodium, magnesium, and calcium. Iron and zinc, while essential for health, are needed in smaller quantities.
How does Magnesium's atomic radius compare to aluminum?
Magnesium's atomic radius is smaller than Calcium's.
Which is more stable EDTA calcium or magnesium?
EDTA forms more stable complexes with calcium than with magnesium. This is due to the higher charge density and smaller size of the calcium ion, which allows it to form stronger bonds with the EDTA molecule.
What is the most abundant substance in the human body is?
Water (H20) and Carbon, for the most part, but there's also traces of other smaller minerals, such as calcium and magnesium.
