The element with an atomic mass unit (amu) of 20 and is a gas is Neon. Neon has an atomic number of 10 and is a noble gas found in the Earth's atmosphere.
The Element Neon has 10 protons and 10 electrons.
Sc, scandium (21), the first metal element in the 3d-block (transition elements); next to calcium (20).
The element neon has 10 protons as its atomic number is 10.
Element number 10 is neon (Ne) and it has 10 protons.
To find a number that is 10 less than 305, you would subtract 10 from 305. So, 305 - 10 = 295. Therefore, the number that is 10 less than 305 is 295.
305 cm is 10 feet.
Ten less than 305 is 295.
10 mm = 1 cm so 305 mm = 305/10 = 30.5 cm. Simple!
It is: 295+10 = 305
305 - 2003 was released on: USA: 10 July 2003
the chemical element of number 10; an inert gaseous element of the noble gas group. It is obtained by the distillation of liquid air and is used in fluorescent lamps and signs
295
10 millimeters = 1 centimeter 305 millimeters = 30.5 centimeters
It is: 295+10 = 305
The element with an atomic mass unit (amu) of 20 and is a gas is Neon. Neon has an atomic number of 10 and is a noble gas found in the Earth's atmosphere.
305cm is 10 feet.
