According to , the number of transistors that could be squeezed onto a silicon chip would double every 18 months. Metcalfe's law Murphy's law Ashby's law Moore's law Megan's law

Moore's law.

Explanation:

Description

Moore's Law states that the number of transistors on a microchip doubles every two years, though the cost of computers is halved.

It also states that we can expect the speed and capability of our computers to increase every couple of years, and we will pay less for them.

Example A computer chip that contained 2,000 transistors and cost $1,000 in 1970, $500 in 1972, $250 in 1974, and $0.97 in 1990 costs less than $0.02 to manufacture today

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
