Will potassium share more properties with calcium or sodium?
potassiumwill share more properties with sodium because both are Alkali metals and have same number of valence electrons.
How many valence electrons are transferred from the nitrogen atom to potassium in the formation of the compound?
Potassium loses one valence electron to the more electronegative nitrogen to form the compound potassium notride
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.
What element has atoms with more valence electrons then kernel electrons?
borin has more valence electrons than kernel electrons
Is covalent gained lost or shared electrons?
Depends on the atom, remember that metals want to loose all valence electrons and non-metals want to gain electrons so that it has 8 valence electrons (similar to noble gases) For example Al (Aluminum) is in group 3, it's a metal so it will lose 3 valence electrons making it have a charge of +3 or AL3+. Another example, F (Florine) has 7 valence electrons, it's a non-metal so it will gain 1 to become stable, making it have a charge of -1 or F1-. Hope this helps Ya! :-P

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.
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.

Which is more likely to form a cation between sodium and calcium?
Sodium is easier to form Na+ then Calcium forming Ca2+. The main reason is because Sodium has got 1 valence electron, which is more unstable than Calcium having 2 valence electrons. It requires less energy to remove one electron from Sodium than two electrons from Calcium. Therefore, Sodium is higher than Calcium in the reactivity series.
How do you know the chemical reactivities of elements?
The farther the valence electron are from the nucleus, the more easily they can be lost therefore the more reactive the element is. i.e potassium would be more reactive than sodium (check their valence electrons)
Why does potassium form compounds?
potassium- element 19, alkali metals, atomic symbol "K" potassium is rarely if ever found in its pure form, this is because it only has one valence electron, the closer an atom is to a totally full or totally empty valence energy level, the more it wants to bond with an element that will give it a full shell, so in the case of covalent bonds, potassium will bond with an atom that has 7 valence electrons or just something that will give the compound 8 valence electrons hope this helped!
Why Ba is more reactive than Ca?
strontium is more reactive than calcium because it is more electropositive. valance electrons of strontium are farther away from the nucleus of strontiium atom than the valance electrons of calcium from nucleus of calcium atom. so the force exerted by the nucleus on the valence electron of strontium is lesser than that exerted by calcium. so the strontium atom can loose its valance electrons more easily. therefore strontium is more electropositive and more reactive than calcium.
How many more valence electrons does magnesium need to have a full outer valence shell?
it needs six more electrons to have a full outer valence shell.
