Answer:
The chemical element neon is classed as a noble gas and a nonmetal. It was discovered in 1898 by William Ramsay and Morris Travers.
Yes neon is a magnetic
-248.6 °C
Neon/Melting point
Answer:
the results of an investigation thank me later
Explanation:
Atomic mass of the parent element =247,
atomic number of the parent element = 95
In the process of β-decay electron leaves the nucleus, so instead of one neutron we get one proton.
Mass of proton≈mass of neutron,
so atomic mass will not change.
Charge of proton =+1, and charge of neutron = 0.
So, we will get atomic number increased by one.
New element (daughter) will have
atomic mass = 247,
and atomic number= 95+1=96
Number 95 - Am (parent),
number 96 - Cm(daughter),
So, from Am-247 we will get Cm-247.
Answer:
Thus, the radius of the helium atom in nanometers is - 0.031 nm
Explanation:
Given that:-
The radius of the helium atom = 31 pm
Considering the conversion of length in pm to the length in nm as:-
1 pm = 0.001 nm
So,
Applying the above conversion factor in the radius of helium atom as:-
Radius = nm = 0.031 nm
<u>Thus, the radius of the helium atom in nanometers is - 0.031 nm</u>
