Which scientist proposed the atom's nucleus contained protons and in what year?
It is the scientist Rutherford. He proposed it in year 1919.
What month does it snow most in japan?
Generally, January and February are the months when it snows the most in Japan, especially in regions like Hokkaido and the Japanese Alps. However, the specific timing and amount of snowfall can vary depending on the region and the year.
What year did Schrodinger make a model of the electrons surrounding the nucleus at a distance?
The Schrodinger equation is from January 1926.
What year did Niels Bohr discover?
Niels Bohr's most famous discovery was the Bohr model of the atom in 1913, which proposed that electrons in an atom orbit the nucleus in fixed energy levels.
What year did Dalton say that Atoms of the same element exactly alike?
John Dalton postulated that atoms of the same element are exactly alike in his atomic theory developed in the early 19th century.
What year did Rutherford say that most of atom's mass is in the nucleus?
1909-1911
What year did Niels Bohr find that most of an atom mass is in the nucleus?
This discovery is from Ernest Rutherford (approx. 1913).
What are 2 atoms that have the same number of protons?
None of the elements of the periodic table have the same number of protons. All elements have their own unique atomic (proton) number which defines how many protons that element has in its atoms. Just a note that the atomic number is also called the proton number. To know which number is which the atomic number is always smaller. The Atomic number gives both the proton and electrion number as these most be the same due to the charges for it to be an atom.
If a certain radioactive substance has a half life of one year how many atoms of the substance remain after 5 years if there are initially 5000 such atoms?
Half life refers to the time required for the change (decay) of a radioactive nucleus to a lighter, possibly more stable, nucleus.Starting with 5,000 radioactive atoms, at the end of first year, half would have decayed leaving 2,500. Following the same pattern, the end of the second year would see only 1,250. By the end of year 5, there would be just 156 radioactive atoms.
Is a ten year old cat's mass mass most likely to be 6 kilograms or 6 grams?
A ten year old cat's mass is most likely to be around 6 kilograms, as 6 grams would be extremely lightweight for a cat of that age and size.
What year had the most blood transfusions?
An exact year is impossible to identify but the most blood transfusions likely occurred during wars due to mass casualties.
What is the most well attended mass of the year?
Probably Easter Sunday, and then Christmas Day.
What year was the nucleus discovered?
1911
What is most likely to have a mass close to 3 kilograms a small feather a five year old cat grown elephant or a peach?
A cat is most likely to have a mass close to 3 kilograms.
Which continent has most of their land mass in the tropics?
Africa has the most land mass in the tropics. The continent is positioned across the equator, resulting in a significant portion of its land falling within the tropical zone, receiving direct sunlight throughout the year.
Which scientist proposed the atom's nucleus contained protons and in what year?
It is the scientist Rutherford. He proposed it in year 1919.
What are inside the Good Friday mass?
On Good Friday there is no mass. It is the only day in the year that there is no mass.
