The latter, usually abbreviated as The Wealth of Nations, is considered his magnum opus and the first modern work of economics.[3] Smith studied social philosophy at the University of Glasgow and at Balliol College, Oxford, where he was one of the first students to benefit from scholarships set up by fellow Scot, John Snell.

After graduating, he delivered a successful series of public lectures at Edinburgh, leading him to collaborate with David Hume during the Scottish Enlightenment.

It is a member of group 14 in the periodic table, along with carbon above it and germanium, tin, lead, and flerovium below.

It is rather unreactive, though less so than germanium, and has great chemical affinity for oxygen; as such, it was first prepared and characterized in pure form only in 1823 by J? Silicon is the eighth most common element in the universe by mass, but very rarely occurs as the pure element in the Earth's crust.

Other artists who are in the line-up for the new season include Nigeria’s Ice Prince, Nneka, Banky W, M. Some of the big names who were featured in the last season include Nigeria’s Tiwa Savage, Davido, Wizkid, Uganda’s Navio and South Africa’s Liquideep.

The outer electron orbital of silicon, like that of carbon, has four valence electrons.

The 1s, 2s, 2p and 3s subshells are completely filled while the 3p subshell contains two electrons out of a possible six. It has a negative temperature coefficient of resistance, since the number of free charge carriers increases with temperature.

Smith obtained a professorship at Glasgow teaching moral philosophy, and during this time he wrote and published The Theory of Moral Sentiments.

In his later life, he took a tutoring position that allowed him to travel throughout Europe, where he met other intellectual leaders of his day.
