Electrons:Electrons are negatively-charged subatomic particles that orbit the nucleus in an electron cloud. Even though they technically have a mass, they behave as waves, not particles.Answer and Explanation: Become a member and unlock all Study Answers Start today. Try it now Create...
What is the most accurate model for electrons of an atom? Models of atom The different models of atom proposed in past are : 1) Dalton's model of atom 2) Thompson's plum pudding model 3) Rutherford's nuclear model 4) Bohr's model ...
To determine the number of valence electrons in the atom of an element A with atomic number 20 and to identify its valence shell, follow these steps:Step 1: Write the Electronic Configuration The atomic number of element A is 2
The representation which shows the number of electrons in different subshells for an atom is named as the electron configuration. The maximum capacity of s, p, and f subshell is 2, 6, 10, and 14 electrons respectively. Answer and Explanation:1 ...
Protons and neutrons have approximately the same mass. However, one proton is about 1,835 times more massive than an electron. Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes ...

ahis force is of electric nature,and the attraction between electrons of one atom to the nucleus of another atom contribute to what is known as chemical bonds. 他的力量是电自然,并且吸引力在一个原子之间电子对另一个原子中坚力量对什么贡献通认作为化学键。[translate]...
Electrons are involved in chemical bonding and reactions. Atomic Structure: The nucleus is the dense core of the atom, containing protons and neutrons. Electron shells are energy levels where electrons reside. The arrangement of electrons determines an atom’s chemical properties and its ability to ...
