What happen when you move hydrogen closer?
It depends what you move it closer to.
Are the physical properties of hydrogen closer to those of nonmetals or metals?
Well, it's a gas, so its properties are closer to nonmetals.
What is the shielding effectand the size of the atomic radius related?
The shielding effect is when nearer electrons block farther electrons from getting closer to the protons, and hence, the nucleus. If the farthest electrons were able to get closer, the atomic radius would decrease because those electrons wouldn't be as far out as they originally were.
Why do elements which exists as isotopes have fractional atomic mass?
Each isotope of an element has a different Atomic Mass, so an average is taken of all the isotopes, but the average is weighted because the natural abundance (%) of each isotope is factored in. If hydrogen-1 is much more abundant than deuterium and tritium, then the weighted average will be closer to 1 than 2 or 3 but not a whole number. The following equation shows how percent abundance factors into the weighted average. (atomic mass A)(X% abundance) + (atomic mass B)(Y% abundance)...=(weighted average of all isotopes of the element)(100% abundance)
Why does hydrogen emit several colors in the Balmer series?
The particular colors emitted by an element reflect the exact amounts of energy that electrons orbiting the hydrogen nucleus give off when they drop from higher energy positions further from the nucleus to lower energy positions closer to the nucleus. Since hydrogen is so small and has so few orbitals, it has only four colors that it emits on the Balmer Series. Elements with high atomic numbers have many more orbitals and thus many more colors.
Who said the mass of an electron is about 12000 that of a hydrogen atom?
its not, its closer to about 1/1800 of a hydrogen atom, the English chemist john Dalton was the first person to discover relative atomic masses and use them properly.
What happen when you move hydrogen closer?
It depends what you move it closer to.
Are the physical properties of hydrogen closer to nonmetals or metals?
nonmetals because hydrogen is a gas
What current Philadelphia Phillies closer was the closer for the astros?
brad lidge!
What are all the gases in a protostar?
Mostly hydrogen (with some helium, deuterium, and lithium). Other elements (all other elements) are added as the date of formation of the protostar comes closer to the current date.
What current Philadelphia Phillies pitcher closer was the closer for the Astros?

What Makes up 75 percent of the sun's mass?
Hydrogen. Actually the figure is closer to73.46% hydrogen. 24.85% is helium.
What happens to the Peru current as it reaches the equator?
It goes from a cool current to a warm current as it gets closer to the equator.
Does the chlorine atoms in hydrogen chloride have a stronger attraction for the electrons than the hydrogen atoms do?
Yes. The electronegativity of chlorine is more than that of hydrogen. As such, the electrons are closer towards chlorine than hydrogen in HCl.
Which element will be closer to the top of the periodic table?
hydrogen (top left) and helium (top right)
Why does the atomic radius decreases as the atomic number increases?
The atomic radius decreases as the atomic number increases due to the fact that there is now a greater quantity of protons in the nucleus emitting greater intramolecular force, pulling the electrons closer towards it. This, thus, decreases the radius.
