The extent of sexual unhappiness is a significant cause for concern, particularly among those organisations adopting a health promotion approach to preventing the onward transmission of HIV. Many charities and other community based HIV organisations across the world have drawn on the broad principles of...
What is the first element on the periodic table? Hint: It has one electron! For an atom of any element (excluding hydrogen), what atomic orbitals contain electrons with the highest energy? Which element has valence electrons closest to nucleus?
What role does electronegativity play in the formation of polar bonds? What is meant by the term electronegativity? What are the trends across and down the periodic table for electronegativity? Explain them, and describe how they are consistent with trends of ionization energy and atom...
Rett syndrome (RTT) is a neurodevelopmental disorder caused primarily by pathogenic loss-of-function variants on the X-linked MECP2gene [1]. It is a rare disorder that affects approximately 1 in 9000 liveborn females [2]. The incidence of males with loss-of-function MECP2 variants, who ...
The need to be aware of global sentinel events is leading to an important function of the program: the periodic publication of whatINSPEARmembers determine by consensus to be important types of antimicrobial resistance heretofore undescribed or of great public health importance (Table 1). ...
Ionization energyincreases across a row on the periodic maximum for the noble gases which have closed shells. For example, sodium requires only 496 kJ/mol or 5.14 eV/atom to ionize it. On the other hand, neon, the noble gas, immediately preceding it in the periodic table, requires 2081 kJ...

On to the sixth row! No matter how carefulyou are, the sixth row would definitellykill you. The sixth row of the periodic table contains several radioactive elements,in- cluding promethium,polonium,astatine,and radon.Astatine is the bad one. ...
