Complete the diagram below to show the electronic structure of an atom of magnesium.2 electrons in outer shell8 electrons in middle shell Mg[2](ii) An isotope of magnesium has a nucleon number (mass number) of 26.Deduce the number of neutrons in one atom of this isotope of magnesium.14...
Frequency of effective collisions increases. 2) Increase in concentration of acid. There will be more particles per unit volume and they are closer together . Frequency of effective collisions increases. 3) Decrease in particle size of magnesium carbonate. Smaller particle size will lead to larger ...
The alkaline earth metals are the elements in group 2 of the periodic table. They are all silvery, shiny metals that are less reactive than the alkali metals. Some common alkaline earth metals are calcium, magnesium, and barium. They have two electrons in their outer shell, so they are sti...

An orbital diagram is a diagram that shows the distribution of electrons in different orbitals of an atom. It can be drawn by following three different principles namely the Aufbau principle, Hund's rule, and the Pauli Exclusion Principle....
What is the orbital notation for magnesium? How to write molecular orbital configuration How to calculate bond order from molecular orbital diagram What are the four quantum numbers for each of the two electrons in a 4s orbital? How to find the orbital quantum number?
All three samples were analyzed for calcium (Ca), magnesium (Mg), sodium (Na), potassium (K), chloride (Cl), sulphate (SO4) and phosphate (PO4) by Ion Chromatograph (Metrohm IC 861). HCO3 was determined by volumetric titration. The Piper diagram shows that parent solutions clustered ...
