What are some examples of where it might be useful to classify elements?
Classifying elements can be useful in various fields such as chemistry to group elements based on their properties and behaviors, in biology to categorize organisms into different taxonomic groups, and in library science to organize books based on subject matter for easier access.
How do you make fireworks at home?
You really should NOT make your own fireworks, unless you are trained to do so (and a trained expert would not be asking this question). If you try and make your own fireworks and you make a mistake, you could injure or kill yourself and people who happen to be near you. Leave fireworks to the experts, or you might regret it for the rest of your life.

Are fireworks at a wedding tacky?
That depends entirely on the wedding. Where, when and who all determine the use of fireworks.

A hand full of firecrackers and a couple of rockets set off in the backyard might not have the same effect.

It is safer to leave fireworks in a closed tin box because if it is not the fireworks might be able to catch oxygen and heat so therefor might be able to expload.
What type of elements have valence electrons?
Elements in every group of the periodic table has some number of valence electrons. The exception is, when it comes to group 18, the number of valence electrons might be considered as either 0 or 8.
What elements have no valency?
The noble gases, or group 18 elements, have oxidation states of zero. However, their chemistries are not as barren as one might expect. Please see the link for the periodic table and individual articles for these elements.
Is it against the Buddhist religion to use fireworks?
The are are no constraints on fireworks. The purpose of using the works might be suspect - an ostentatious show of wealth, disruption of other activites etc.
Do fireworks cost less during holidays?
Some might, due to sales and all.
Is it possible that an unknown group in the periodic table might be found?
This is to my opinion not very probable, though never say impossible: Today Mendelejev's Periodic Table looks rather incomplete, there were no 'transition' elements in it (group 3 - 12)
What else might elements might be named?
Elements may also be named for the place where they were discovered or developed

Which block of elements do halogens belong to?
7A, or the older 17 block. Fluorine, chlorine, bromine and iodine. -------------- You might also be asking what larger classification the halogens belong to: nonmetals. Please see the link.
What group number identify in a numbering system that uses A and B?
In a numbering system that uses A and B, the group number typically refers to the position or classification of elements within a periodic table or a specific set of data. For example, in the context of chemistry, group A might represent main group elements, while group B could signify transition metals. The specific meaning can vary based on the context, so it's essential to clarify the system being used.

Do Australian people play with fireworks at Christmas?
Not legally. Fireworks are illegal for the general public in Australia. Some community groups and even churches might apply for a licence to have fireworks as part of their "Carols by Candlelight" but it is illegal for the general public to set off fireworks, and the authorities have been increasingly clamping down on the activity. Fireworks are classified as Dangerous Goods. Australia is prone to bushfires at the best of times, but Christmas occurs during summer in Australia, and this is prime bushfire season. The combination of fireworks and tinder-dry bushland would be catastrophic. Only in the Northern Territory can the general public purchase fireworks for recreational use, but the approved period to purchase and use fireworks is restricted to 1 July each year. There are numerous fireworks displays at public places on New Year's Eve but these are conducted by professional organisations, and sponsored by councils and/or community groups.
