Why was Bohr's theory for the hydrogen atom initially accepted and why was it ultimately discarded?

Because it worked perfectly for the hydrogen atom, but not for any other element.

Why is H also an accepted symbol for a proton?
H is an accepted symbol for a proton because a proton is the nucleus of a hydrogen atom. Since hydrogen atoms consist of just one proton and no neutrons, the symbol H is used to denote both the element hydrogen and a single proton.
Which element in the core of a high mass star leads ultimately to a supernova explosion?
The Answer may be hydrogen. Hydrogen moves to the suns core as it starts to die, or explode. hydrogen is a very flammable gas. A star, like the sun is surrounded by heat. this heat will ignite the hydrogen gases as it moves to the core. This ignition of the hydrogen will cause the star to expand in size and increase in temperature.
When water dissociates each water molecule splits into?
Initially, each water molecule splits into two hydrogen atoms and one oxygen atom. These single atom forms of hydrogen and oxygen are highly reactive and soon pair with one another to form diatomic molecules of both hydrogen and oxygen.
What were atoms heavier than helium were made by?
Atoms that are heavier than hydrogen were made by nuclear fusion after the big bang. Initially, only the lightest element, hydrogen, was present. However, after the universe cooled, hydrogen atoms fused to form helium. Later, the fusion of these atoms led to the formation of the other elements.
Is 'hydrogen' a metal a nonmetal or a metalloid?
In the Scientific Community, Hydrogen is accepted as a non-metal. One of the most common reason's for this is because Hydrogen is a gas (at room temperature). A statement that can invalidate this is, Mercury is a metal, but is a liquid (at room temperature). Experiments that justify Hydrogen's placement amongst the Alkali Metals include very low temperatures and very high pressures, at which Hydrogen acts like a metal, being more electrically and thermally conductive than silver. Other facts that propose Hydrogen as a metal are fairly simple. All alkali metals react violently with Oxygen, forming an oxide, or rust. Hydrogen can be burned with Oxygen, to create Hydrogen-Oxide (Water, Hydrogen Peroxide, etc). To support this even further, rust is a crystal. The reason why water expands when frozen is because it assumes a crystalline structure.
What happens during the proceess of photsytheies?
Water is split into hydrogen & oxygen, the hydrogen is added to CO2 (to make sugar) and the O2 is discarded.
Hydrogen ions are accepted by?
bases
Where does hydrogen in glucose ultimately come from?
it comes from water molecules :P
Where were helium and and hydrogen formed?
Hydrogen was initially formed in the 'Big Bang' which initiated this universe. Helium is formed by the fusion of hydrogen atoms, inside stars. This reaction is what causes stars to shine, and give off heat.
When water is heated most of the energy that water initially absorbs is used to?
It breaks the hydrogen bonds between the water molecules
When hydrogen is added to ch3ch2chchch3 the reaction is an?
... addition reaction; the hydrogen molecule is split, one of its atoms is added to each carbon atom that is initially double bonded, and an alkene becomes an alkane. --- ... known as hydrogenation.
When liquid water is heated most of the energy that the water initially absorbs is used to raise the temperature of the water or break hydrogen bonds?
the .
Where apart from air does elements come from?
The earth itself is the main source - ultimately everything but hydrogen came from exploding stars.
Why is H also an accepted symbol for a proton?
H is an accepted symbol for a proton because a proton is the nucleus of a hydrogen atom. Since hydrogen atoms consist of just one proton and no neutrons, the symbol H is used to denote both the element hydrogen and a single proton.
What is the fuel spent off in many stars like the sun?
Stars' energy comes from the fusion of hydrogen atoms into helium atoms, initially.
What will the deamination of amino acids produce?
Deamination of amino acids will result initially in the formation of ammonia. It has a compound of nitrogen and hydrogen with the formula NH3.
