Explain the difference between an atom and an element. What is the name of the element with a valence electron configuration of 4s^24p^4? What is the name of the element with a valence electron configuration of 2s^22p^2? Which of the following elements is an alkali metal? (a) Ca (b...
What's the difference between atomic and mass numbers in an atom? From the atomic mass (mass number), one can deduce the number of ___ in each atom of an element. The mass number of an element can be easily approximated by adding together the number of ___ i...
Atoms are the basis of all the elements in the universe, the building blocks of all visible matter, and the secret to nuclear power.
What is the difference betweenElements and Compounds? • Elements are pure substances, which consist of only a single type of atom. In a compound, two or more elements are chemically bound together. • In a compound, elements are present in defined ratio. ...
What is the difference between Atom and Molecule? Atoms are single elements whereas molecules are two or more atoms combined together. Molecules have bonds between atoms. They have intra-molecular and intermolecular forces, but atoms have interatomic forces only. ...
So far as we can tell, by all experiments so far, the difference between the electron and the muon is nothing but the mass. Everything works exactly the same for the muon as for the electron, except that one is heavier than the other. Why is there another one heavier; what is the ...
alkali metals (the first column of elements), alkaline earth metals (the second column of elements), halogens (the next-to-last column of elements), and noble gases (the last column of elements) Each row of elements on the periodic table is called a period. atoms 原子 Atomic Number 原...
An atom is the basic unit of matter forming chemical elements, consisting of electrons, protons, and neutrons, while a cell is the fundamental unit of life, composed of various molecules and capable of self-replication. Difference Between Atom and Cell ...
Difference Between Element and Factor Table of Contents ADVERTISEMENTKey Differences Elements are basic constituents that make up a complex structure or concept, implying they are essential and cannot be broken down further without losing the essence of the whole. On the other hand, factors are varia...
