In Lewis dot notation aluminum has three dots as it is group 13 and has 3 valence electrons.
Parentheses are used for the formula Al(OH)3 to indicate that the hydroxide group (OH) is grouped together and that there are three of them bonded to the aluminum atom. This notation helps to clarify the composition and structure of the compound.

The name given to Al is simply "Al".
These would be the elements in group 16. The elements in group 16 have six valence electrons. Those valence electrons are represented in a Lewis diagram by surrounding them with six dots. When drawing a diagram for an element with six valence electrons, there should be two pairs of dots (four total), and two separate dots.
Fluorite has a cubic crystal structure, meaning that its crystal lattice is composed of repeating cubes. The atoms or ions are arranged in a face-centered cubic arrangement, with fluoride ions occupying the lattice points and calcium ions occupying the octahedral sites within the structure.

One Al and three Cl
it is a mass structure as concrete is filled in the steel tubes to make it sturdy
In the Lewis structure for AlF3, aluminum (Al) is surrounded by three fluorine (F) atoms. Aluminum has three valence electrons and each fluorine has seven valence electrons. The structure will show three single bonds between Al and each F atom, with the F atoms each having a full octet of electrons.
Construction of the Burj al Arab hotel began in 1994. The biggest challenge was regulating the temperature inside the structure.
