Atomic radius and electrons because opposite charges attract, and more protons creates a stronger charge. The greater attraction draws the electrons closer to the protons, decreasing the size of the particle. Therefore, atomic radius decreases. Down the groups, atomic radius increases. This is because there are more energy levels and therefore a greater distance between protons and electrons. In addition, electron shielding causes attraction to decrease, so remaining electrons can go farther away from the positively charged nucleus. Therefore, size (atomic radius) increases. The following table summarizes the main phenomena that influence the atomic radius of an element: The electrons in the
Passenger Movement Charge negative impact of the pilots' dispute of 1989. The departure tax was raised again in 1994 to A$25 to offset the additional cost of tourism promotion expenditure, specifically an additional A$80 million allocated to the development of new tourism products. Since its name change to passenger movement charge in 1995, the rate of the PMC has changed on several occasions. In most cases the Australian federal government has given a rationale for rate increases. Australia's departure tax is one of the highest in the world. Few jurisdictions levy taxes on departing international passengers, although some charge airport fees to cover
