hi amail how are you :)

Yttrium
Atomic Weight 88.90585
Density 4.472 g/cc
Melting Point 1526.C
Boiling Point 3345.C
Yttrium is rarely seen in pure form and has no applications as a metal. Yttrium-aluminum-garnet (YAG) is important in lasers and yttrium is also used in the phosphors of color television sets (the old CRT kind).

Maser - Microwave Amplification by Stimulated Emission of Radiation

Please post atomic number of Yttrium. Atomic number is more important than atomic weight.

Resistor

A resistor is a device that has electrical resistance. It is used in an electric circuit for protection, operation, or current control. The amount of resistance can be identified by the color bands on the resistor.

there you go akhl atomic numba added :D

Rheostat
used in applications that require the adjustment of current or the varying of resistance in an electric circuit.

Thermometer - device to measure temperature

Transformer - transfers electrical energy from one circuit to another through inductively coupled electrical conductors.

You had to write a scientific term starting with the letter 'R'.

Rainforest

A rainforest is a biome that is normally found in regions of the world near the equator. Rainforests receive a large amount of rainfall and are home to a wide variety of biological species, both plants and animals.
