What part of the atom does the word nuclear refer to?
A concept or model of the atom characterised by the presence of a small, massive nucleus at its centre.
What is the main concept of the periodic law?
There amount of protons, neutron's , and electrons, the smallest amount is 1 and so on.
Outer shell electrons are known as hybrid valence vector or transitional electrons?
Outer shell electrons are called valence electrons. They are involved in chemical reactions and determine the reactivity and bonding behavior of an atom. The concept of hybridization refers to the mixing of atomic orbitals to form new hybrid orbitals, which can help explain the geometry of molecules.
Concept of oxidation and reduction?
a reversible chemical reaction in which one reaction is an oxidation and the reverse is a reduction
What was the contribution of H. Moseley in the development of atomic theory?
He determined the number of positive charges in the nucleus of an atom. He was the first one to bring the concept of atomic number.

What contribution did Aaron Beck make the to the treatment of depression?
Beck developed the concept of the negative triad.
Which scientist discovered Movement of electrons about a central nucleus is a concept?
dalton
Ernest Rutherford's contribution to the atomic structure due to the gold foil experiment?
Ernest did an experiment where he shot alpha particles into a gold foil that proved the concept of a nuclear atom, that is an atom with a nucleus made of protons and neutrons and have electrons moving around the nucleus in some way. His experiment did not show the position of electrons or energy levels or even how they moved.
What is the science concept on Lava lamp?
it is the flow of electrons moving throw the liquid
Explain free electron concept and electric current?
the flow of electrons in semi conductor is called electric current. the electrons revolved around the nucleas is called free electrons

What month is holi?
Most of the annual holy days are concentrated in the month of Tishrei. However, Judaism doesn't have the concept of a holy month.
Do photons conduct electricity?
No. Electricity is the movement of electrons, and photons have no electrons to move. Photons are the gauge particles for the electromagnetic force, but that's a different concept.
What was general motor's Alfred sloan's major contribution to the automaking industry?
Alfred Sloan's major contribution to the automobile industry was having automobiles have model years. This concept also led to planned obsolescence.
