What happened to hydrogen bombs?
Hydrogen bombs still exist and are considered among the most powerful weapons in the world. These bombs use nuclear fusion to release an immense amount of energy, and they are designed to create explosions far more destructive than atomic bombs.
Which is the lightest substance among these four 1oxygen 2nitrogen 3hydrogen 3carbon?
Hydrogen is the lightest substance among these four elements. It has the lowest atomic number and atomic weight, making it the lightest element on the periodic table.
Hydrogen lithium and sodium all have one valence electron Which element has the smallest atomic radius?
Among hydrogen, lithium, and sodium, hydrogen has the smallest atomic radius because it has the fewest number of electron shells and the smallest number of electrons, leading to a smaller atomic size.
Does sodium have the smallest atomic size?
no, hydrogen has the smallest size among all elements
Which atomic particle has the least mass?
An electron has the least mass among the three fundamental particles of an atom, which includes protons and neutrons.
What elements did John Dalton discover the atomic weights of?
John Dalton determined the atomic weights of several elements, including hydrogen, oxygen, carbon, nitrogen, and sulfur, among others. He used hydrogen as the reference point with an atomic weight of 1, assigning relative weights to other elements based on their combinations with hydrogen. Dalton's work laid the foundation for the modern understanding of atomic theory and the relative weights of elements. His findings were crucial in advancing the field of chemistry in the early 19th century.
Which element has the smallest atomic size from first 4 periods?
Helium has the smallest atomic size among elements in the first four periods of the periodic table. It has the smallest atomic radius due to its high effective nuclear charge and low electron-electron repulsion.
What elements have an atomic mass of less than 10?
Elements with an atomic mass of less than 10 include hydrogen (1.008), helium (4.0026), lithium (6.94), beryllium (9.0122), and boron (10.81). Among these, hydrogen, helium, lithium, and beryllium all have atomic masses below 10, while boron is just above. These elements are primarily found in the first two rows of the periodic table.
What is the largest biological level among these cell organ tissue or molecule?
The largest biological level among the given options is organ
What is the hydrogren bomb?
A hydrogen bomb, also known as a thermonuclear bomb, is a type of nuclear weapon that releases energy through the fusion of hydrogen isotopes. It is more powerful than atomic bombs, which rely on fission reactions. Hydrogen bombs are capable of causing massive destruction and are considered to be among the most powerful weapons in existence.
Is The atomic number is always equal to the atomic weight?
No.The atomic number is dependent on the number of protons. The atomic weight is dependent on the number of protons and neutrons. As almost every element has some neutrons in its nucleus the atomic number will never be equal to the atomic weight.The one possible exception is Hydrogen with a single proton. However there are two isotopes of hydrogen: deuterium and tritium. Deuterium has one proton and one neutron. Tritium has one proton and two neutrons. Therefore when taken as a whole the atomic weight of hydrogen will always be slightly greater than 1g/mole.
Which element hasthe highest binding energy per nucleon Hydrogen Lithium Helium or Beryllium atomic?
Helium has the highest binding energy per nucleon among Hydrogen, Lithium, Helium, and Beryllium atomic elements. This is due to helium having a more stable nucleus because of its higher number of protons and neutrons, leading to stronger binding forces.
