Oxygen ☻oxides:

There is a gradual transition from basic oxides to acidic oxides from the lower left to the upper right in the periodic table. Oxides of metallic elements are generally basic oxides, which either react with water to form a basic solution or dissolve in aqueous acid. In contrast, oxides of nonmetallic elements are acidic oxides, which either react with water to form an acidic solution or are soluble in aqueous base. Oxides of intermediate character, called amphoteric oxides, are located along a diagonal line between the two extremes. Amphoteric oxides either dissolve in acid to produce water or dissolve in base to produce a soluble complex ion. (Radioactive elements are not classified.)

Trivia about twice Nobel Prize-awarded scientist – and teacher – Prof. Marie Curie (1867–1934), center in photo with four of her students:

• She was born Maria Skłodowska, the youngest of five children of a teaching couple.

• She attended an illegal “floating university” in her youth – a night school changing locations to elude authorities during a time of czarist Russia's occupation of Poland, that forbade women to study at university.

• At age 16, Curie starts work as a private tutor and later governess to help support her elder sister Bronya’s medical schooling in Paris. The agreement is that Bronya will return the favour after graduating.

• Outside of work, Curie spends spare time teaching the illiterate children of her employer’s peasant laborers. She is 24 when she finally joins Bronya in Paris to begin studies at the University of Sorbonne.

• By the time of her marriage to physicist and collaborator Pierre Curie in 1895 (with whom she is awarded her first Nobel Prize in Physics 1903 for research on radiation), Marie holds two master's degrees – in physics and math – and decides to earn a certificate that will allow her to teach science to young women.

• In 1897, she becomes the first lecturer at France's most renowned teacher training institution for women, introducing lab work to the physics curriculum.

• In 1906 she becomes the first woman to teach at the University of Sorbonne.

• Also in 1906, Marie Curie helps start and run a cooperative school with a number of other professional parents who disapproved of the rigid French school system.

One of the pupils is Marie Curie’s oldest daughter Irène, who grows up to join her mother’s research staff at the Radium Institute, along with husband Frederic Joliot.

The couple Joliot-Curie discovered artificial radioactivity and were jointly awarded the 1935 Nobel Prize for Chemistry.

Why Chlorophyll is Green in Color

Because it absorbs red and blue light strongly but is transparent to green light, pure chlorophyll has a strong green colour.
