Answer:

Physical Properties of Aluminum

Aluminum has a lower density than any other commercial metal except magnesium. Given the right type of surface, aluminum makes an excellent reflector, especially for ultraviolet light.

Aluminum is an odorless, tasteless, silvery white metal. With increasing silicon and ductile and quite soft. The aluminum crystal has a face centered cubic structure.

The concentration of the lattice in the less pure metal results from the formation of impurity segregations. Purity also affects most other physical properties.

Aluminum has a lower density than any other commercial metals except magnesium.

Aluminum may also be used as a selective cold or hot wall or as a body approximating to the effect of a black body. In the infrared region the reflectivity of aluminum is exceeded only slightly by that of gold and silver.

Chemical Properties of Aluminum

1. Reaction of Aluminum with Air

Generally, Aluminum metal does not react with air as its surface is covered with a thin layer of oxide that helps protect the metal from attack by air. However, in case the oxide layer gets damaged, and the Aluminum metal gets exposed, it reacts again with oxygen forming amphoteric oxide (Aluminum (lll) Oxide), Al2O3.

4Al (s) + 3O2 (l) → 2Al2O3 (s)

Explanation:

Properties of P-Block Metals These metals have classical metal characteristics that they are shiny, good conductors of heat and electricity and also, they lose electrons. They have high melting points and react with non-metals to form ionic compounds.

Radium decays to form radon. Which equation correctly describes this decay? Superscript 226 Subscript 88 Baseline Upper R a righ

KiRa [710]

Answer: 226 Subscript 88 Baseline Upper R a right arrow Superscript 222 Subscript 86 Baseline Upper R n + Superscript 4 Subscript 2 Baseline Upper H e

Explanation:

Alpha decay : When a larger nuclei decays into smaller nuclei by releasing alpha particle. In this process, the mass number and atomic number is reduced by 4 and 2 units respectively.

The general representation of alpha decay reaction is:

$^{A}_{Z}\textrm{X}\rightarrow ^{A-4}_{Z-2}\textrm {Rn}+ ^{4}_{2}\textrm{He}$

Representation of Radium decays to form Radon

$^{226}_{88}\textrm{Ra}\rightarrow ^{222}_{86}\textrm {Rn}+ ^{4}_{2}\textrm{He}$

Thus 226 Subscript 88 Baseline Upper R a right arrow Superscript 222 Subscript 86 Baseline Upper R n + Superscript 4 Subscript 2 Baseline Upper H e represents alpha decay.
