What is the mass of a ptoton in amu's?
The mass of a proton is approximately 1.007276 atomic mass units (amu). This value is often rounded to 1.007 for simplicity in various calculations. Protons are one of the primary components of atomic nuclei, along with neutrons.
When the atomic nuclei of hydrogen and lithium are squashed together what is the element produced?
When the atomic nuclei of hydrogen (specifically, hydrogen isotopes like deuterium or tritium) and lithium are fused together under extreme conditions, they can produce helium. This process occurs in stellar environments, such as in stars where fusion reactions take place. Additionally, the fusion of lithium with hydrogen can also produce isotopes of helium, along with other particles like neutrons.
What did lise meitner contribute to the atomic theory?
Lise Meitner was a pioneering physicist who contributed significantly to the understanding of nuclear fission. Along with Otto Hahn, she discovered that when uranium nuclei absorb neutrons, they can split into smaller nuclei, releasing a substantial amount of energy. This discovery laid the groundwork for the development of nuclear energy and atomic bombs. Meitner's work was instrumental in explaining the mechanism of fission, although she did not receive the Nobel Prize for it, which was awarded to Hahn alone in 1944.
What makes the atomic radius change along the periodic in the periodic table?
Along a period, nuclear charge increases. hence, atomic radius decreases.
What is the effect of an additional electron have on atomic size?
According to me the atomic size of an atom increases or decreses with the change in the number of shells. As atomic size is defined as the distance between the nucleus and valence shell of an atom. So, the addition of an electron does not effect the atomic size. As we can see in the periodic table that while moving along a group the number of electrons increases along with increase in no. of shells, while the atomic size tends to be increase with addition of shells and neglecting the addition of electrons. Same is the case while moving along a period. Atomic size decreases while the attraction between increased nuleus charge increases . Thus the size of the atom decreases.
Symmetrical bond along the axis between two nuclei?
A symmetrical bond along the axis between two nuclei refers to a sigma bond. In a sigma bond, the electron density is concentrated along the axis connecting the nuclei, resulting in strong overlap between the atomic orbitals involved in bonding. This type of bond allows for free rotation around the bond axis.
What is the symmetrical bond along the axis between the two nuclei?
sigma bond
What is a bond that is not symmetrical along the axis between two atomic nuclei?
A polar covalent bond is a bond that is not symmetrical along the axis between two atomic nuclei. In this type of bond, electrons are unequally shared between atoms, resulting in a slight negative charge near the more electronegative atom and a slight positive charge near the less electronegative atom.
What bond is not symmetrical along the axis between two atomic ions?
pi bond
What letters are horizontal and vertically symmetrical?
The letters that are both horizontally and vertically symmetrical are "H," "I," "O," "X," and "W." These letters maintain their appearance when flipped along both axes. Other letters may be symmetrical along one axis but not the other. For example, "A" is vertically symmetrical but not horizontally.
What is a process in which atomic nuclei of unstable isotopes release fast-moving particles and energy?
Nuclear decay is the process in which atomic nuclei of unstable isotopes release fast-moving particles, such as alpha or beta particles, along with energy in the form of gamma radiation. This process is also known as radioactive decay and results in the transformation of the unstable isotope into a more stable one.
What is a fission equation?
A fission equation describes the splitting of an atomic nucleus into two or more smaller nuclei, accompanied by the release of a large amount of energy. An example of a fission reaction is the splitting of a uranium nucleus into two smaller nuclei, along with the release of neutrons and energy.
What force holds nuclei of atoms together?
The force that holds nuclei together is the strong nuclear force. This force is responsible for binding protons and neutrons within the atomic nucleus. It is one of the four fundamental forces in nature, along with gravity, electromagnetism, and the weak nuclear force.
Who first observed the fusion of light nuclei and in what year?
The fusion of light nuclei was first observed in 1938 by scientists Otto Hahn and Fritz Strassmann, along with physicist Lise Meitner. This experiment led to the discovery of nuclear fission, which laid the groundwork for nuclear energy and atomic weapons.
Where does the new cell wall start?
The new cell wall forms along the cell plate that forms between the two daughter nuclei of a plant cell.
Whats the process of splitting the atom called?
The process of splitting the atom is called nuclear fission. In nuclear fission, a heavy atomic nucleus is split into two or more lighter nuclei along with the release of a large amount of energy.
What happens to plants cells during cytokinesis?
A cell plate forms between the two daughter nuclei, along which a new cell membrane and cell wall will be laid.
