Magnesium is smaller than calcium because it has less shells of electron although both elements have the same number of valence electrons calcium has one more shell. However sodiums electron configuration is 2.8.1 which gives it three shells of electron- the same as magnesium it also has less protons in it's nucleus so it appears that sodium is smaller than magnesium not the other way around. Hope this helps :)
What else can I help you with?
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.
Why is it easier to remove an electron from a sodium atom than from a magnesium atom?
Phosphorus has a higher energy level so it pulls harder on its electrons.
Why is the ionistaion energy of magnesium higher than that of sodium?
because ionization energy increases from left to right on the periodic table. Ionization energy is the amount of energy needed to take an electron away from the atom, or the energy needed to ionize it. Since Sodium is more likely to give up an ion to complete the octet rule, it has a higher ionization energy.
Is calcium higher than sodium in the electrochemical series?
Yes it is. Calcium atom loses electrons more readily in cell reactions than in reactions with air, water and dilute acids.
Which is the smallest atom magnesium calcium barium or strontium?
Strontium is the smallest atom among magnesium, calcium, barium, and strontium. This is because as you move down a group in the periodic table, atomic size increases due to the addition of more electron shells. Strontium is located lowest in the group 2 elements, so it has the smallest atomic size among the four elements listed.
Compared to the atomic radius of a sodium atom the atomic radius of a magnesium atom os smaller the smaller radius is primly a result of the magnesium atom having?
The smaller atomic radius of a magnesium atom compared to a sodium atom is primarily a result of the increased nuclear charge in magnesium due to the higher number of protons. This increased nuclear charge pulls the electrons closer to the nucleus, resulting in a smaller atomic radius for magnesium.
What is the most common types of atom in your bodies?
Phosphorus, hydrogen, calcium, carbon, oxygen, nitrogen, magnesium, sulfur, potassium, and sodium
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.
How is an atom of the element sodium structurally different from an atom of magnesium?
A sodium atom has 11 protons and 11 electrons including 1 outer shell electron A magnesium atom has 12 protons and 12 electons of which 2 are in the outer shell. Sodium loses its valence electron more easily than magnesium does, making the sodium much more reactive.
Which is the smallest atom out of calcium beryllium magnesium and strontium?
Beryllium (Be) apexvs
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.
In the the mixture sodium chloride is sodium the smaller atom?
Sodium chloride is a chemical compound, not a mixture.
What is the most abundant atom in the human body?
The most important cations in the human body are sodium, potassium, magnesium, and calcium ions
Why is calcium more reactive than magnesium?
Calcium is more reactive than magnesium because it is larger than a magnesium atom because it has one more energy level. Valence electrons are on the outermost occupied energy level in the atom and they cause the atom to react, and thus the further the Valence electrons are from the nucleus, the more reactive they are. Therefore, calcium is more reactive than magnesium because the valence electrons on the calcium atom is farther from the nucleus.
Oxygen fluorine sodium magnesium aluminium and neon which one is a single atom?
neon
What examples of an atom?
There are many examples of atom, 106 in fact. Look at the Periodic Table of the elements.
A calcium atom is larger than a calcium ion because?
a calcium atom is larger because it contains more electrons than a calcium ion. When a calcium atom loses electrons to become a calcium ion, it becomes smaller due to the loss of electron-electron repulsion, causing the remaining electrons to be pulled closer to the nucleus, resulting in a smaller size.
