Are you scared about your ward's performance in chemistry or scared of putting your ward in the science class when he or she gets to senior secondary school (first year)? I remember when I was in senior secondary school (first year), I used to dread being in a chemistry class or taking any chemistry examination until I realized it was just about determination and focus and so started reading chemistry books that broke down the complexity of elementary chemistry. What if there was a way you could boost your wards buoyancy in chemistry? chemistry) by Omoyeni A.D. (University of Ibadan) This book contains: 📕 10 Major topics in the beginners chemical science. 📕 Brief summary after each topic. 📕 Exercises that can be done after each chapter. 📕 Model exam of 50 questions at the end of all chapter which prepares students for any science examination. 📍 The book is highly useful and recommended to junior secondary school students aspiring to study science in senior school.

The Nobel Prize is the highest award to a scientist. There are and have been very many scientists in the world, but just over a hundred of them have been awarded the Nobel Prize and they received it for the most outstanding discoveries. Three of the Nobel Prizemen for 1932 were Murphy, Urey and Brickwedde. It was thought previously that there was only one hydrogen on Earth, that with an atomic weight of one. Murphy and his colleagues discovered a second hydrogen, twice as heavy. This was the hydrogen isotope having the atomic weight two. Isotopes are varieties of atoms with the same charge but different atomic weights. In other words, the nuclei of isotopic atoms contain an equal number of protons but different numbers of neutrons. Isotopes are known for all the chemical elements: some of them exist in nature: others have been obtained artificially by means of nuclear reactions. The hydrogen isotope whose nucleus is a bare proton is a bare proton is called protium and its s

In most cases, you shouldn't and must not expect your Chemistry teacher to teach you all you need to know in chemistry. Most times, due to limited time and resources, The teacher will only teach you based on the syllabus and will not bother to explain some mysterious facts in chemistry to you. Worst enough, some teachers strictly hide these facts because they just want to be above their students in terms of knowledge. Here are ten facts your Chemistry teacher may never tell you. 1. The word ALKALI is derived from the Arabic word ALQILI which means "plant ash." 2. Alkaline 'earth' metals are called so because the early alchemists believed that any element whose compounds are insoluble in 'water', unchanged by ' fire ' and unburnt in ' air ' is ' earth '. For example, Calcium has the compound Calcium oxide which possesses these properties. 3. ' Aldehyde ' literally mean ALcohol DEHYDrogEnated . 4. The word Pa
