Charge number having stripped off all electrons, the charge number is identical with the atomic number "Z", which corresponds to the number of protons in ordinary atomic nuclei. Unlike in chemistry, subatomic particles with electric charges of two elementary charges (e.g. some delta baryons) are indicated with a superscript "++" or "−−". In chemistry, the same charge numbers are usually indicated as superscript "+2" or "−2". In particle physics, the charge number is a (derived) flavor quantum number. For color-charged particles like quarks and hypothetical leptoquarks, the charge number is a multiple of 1/3. Charge number Charge number ("z") refers to a
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
