And even though pilots flying for large American airlines earn good pay, most such aviators don't work for the big carriers. The majority of commercial airline pilots fly for small regional carriers, earn starting pay around $20,000 yearly and have little job security.
These are aluminum atoms. An atom is the smallest particle of an element that has the properties of that element. Some properties of aluminum are: shiny, silver colored, fragile, and thin. Each element has its own type of properties.
Rubidium also has large atoms, but its atomic radius is almost 30 pm less than cesium's. Why are cesium atoms so big? Cesium has a large valence shell and a relatively low effective nuclear charge. The valence shell (the outer 'peel' of the atom) is largest in atoms at the bottom of the periodic table.A low nuclear charge means that electrons can wander further, on average, from the nucleus.ubidium also has large atoms, but its atomic radius is almost 30 pm less than cesium's.
