particles that balanced the negatively-charged electrons. This idea, together with research into radioactivity, led Ernest Rutherford to the discovery of the atomic nucleus in 1911. Rutherford saw the nucleus as the home of these positively-charged particles (now calledprotons). Further experiments on...

Here we show that the volume of the central subdivision of the bed nucleus of the stria terminalis (BSTc), a brain area that is essential for sexual behaviour 3,4 , is larger in men than in women. A female-sized BSTc was found in male-to-female transsexuals. The size of the BSTc ...
What is an atom made of? Three subatomic particles: – Proton – Neutron – electron + PROTONS + Positively charged subatomic particle Found in the nucleus of an atom – Center of the atom Each proton is assigned a charge of 1+. Each nucleus must contain at least one proton. Mass is eq...
