boron. The symbol of boron is a just a capital B. The atomic number of boron is 5. Boron’s mass is 10.811 grams. Boron has 5 protons, 6 neutrons, and 5 electrons. The Periodic Table lists elements in numerical order from the smallest atomic number to the largest atomic number. That is why boron is the 5th element on the Periodic Table. It comes after beryllium and before carbon. Boron was discovered on June 30th in 1808. It was discovered by French chemists, Louis-Jaques Thénard and…

Have you ever heard the phrase, “the human body is a walking periodic table?” Well if not that then the saying that chemistry is all around you is probably relatable. The truth of the matter is that chemistry isn’t just around you, it also occurs inside of you as well! That’s right the body has chemical reactions happening all the time and you don’t even know it. Some of the ways that the elements are distributed throughout the body are in the bones, blood, metabolism, genetics, and even…

can be found in different oxidation states, that is, different ionic states e.g. Iron (Fe) has two oxidation states, Fe (I) and Fe (II). This means that Iron can have the ionic form of Fe+2 or Fe+3. There is a density trend on the Periodic Table, but…

paper is to find out what material is the gold crown ring made out of. What is interesting about this topic is that there is a lot of ways to study the gold crown ring. For example, you can test the mass, volume, and density of the ring. In the periodic table Au is the symbol for Gold, it’s atomic number is 79. The Properties of Matter are Mass, Weight, Volume, and Length. Each property has its own way of working with different types of things. It is believed that the material of the crown in…

In this class, the diverse learner pairs with peers within the group who help if the diverse student has a problem understanding. Scientific discourse is written in the carbon atom group worksheet. This is one of Hanauer 's components. If the diverse student cannot understand the worksheet, the peer pairing helps the diverse student with language or reading. The teacher monitors visiting each group asking questions. Teacher looks for understanding in the diverse learners. If the diverse…

Currie radioactivity is now frequently used to treat cancer and has the potential to save lives. Marie Currie was a powerful figure who benefitted society’s view of women through her winning of two Nobel Prizes, discovering radioactivity and two periodic table elements, and founding…

Mendeleev conjures up the sole image of a periodic table, secure and immutable with all its ordered numbers and letters marching along in dependable patterns. More than one hundred years ago in Imperial Russia, the name Dmitri Mendeleev would call to mind séance scandals, economic tariffs, hot air balloon rides, a nationwide push for the metric system, bigotry charges, and student protests. This was the Mendeleev that Russia knew and (mostly) loved. The periodic table was just a particularly…

protons, and atomic mass is the mass of the element. The Symbol for Calcium is `Ca’ and the atomic number is 20, and the mass number is 40.078 u. Family. The periodic table is classified into groups and every group(row) has its own properties. Calcium is in group 2 ,and this is the second most reactive group of the periodic table. Each of the elements in group 2 has two electrons in their outer shell. “This group is called Alkaline Earth metals, they are called this because when they are…
