8. In two separate experiments, researchers used laser beams to confine 400 atoms (each) of Na and K in a volume 1.0x10–15 m3 (for a fraction of a second), at a Temperature of 0.00024K (the lowest ever reached for a gas). How many times faster/slower would K atoms be effusing than Na atoms? (1) K atoms effuse 0.77x faster (2) K atoms effuse 0.77x slower

The answer is 3,5g co

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.

☆ionisation energy increases across a period from na -> ar☆ionisation energy decreases down a group from li -> fr☆ionic radius decreases across a period from na -> cl☆ionic radius increases down a groupfrom f -> ii hope it clarifies your doubts
