electrons are in a cloud outside the nucleus
Core electrons are the inner electrons of an atom that are tightly held by the nucleus and are not involved in chemical reactions. These electrons are typically found in filled electron shells closer to the nucleus.
Ok, I think you mean electons. The nucleus is made up of protons and neutrons, surrounded by electrons. An electron has a negative charge. It is so light, it has negligible mass. The atom Hydrogen has only one proton as its nucleus, surrounded by its one electron. Oxygen has, of the top of my head, 8? electrons. These electrons move in orbitals around the proton. Without going into complicated detail, that's all I can tell you I'm afraid.
It describes the most likely locations of electrons in atoms.
A negatively charged electron cloud surrounding a positively charged nucleus. Reason: The nucleus contains positively charged protons and neutral neutrons. The positive nucleus is surrounded by a negatively charged electron cloud.
The electron cloud. The atomic radius roughly describes the distance from the nucleus to the electron cloud.
The electron cloud model best describes the organization of electrons around the nucleus of an atom.
A unit of matter, the smallest unit of an element, having all the characteristics of that element and consisting of a dense, central, positively charged nucleus surrounded by a system of electrons. The entire structure has an approximate diameter of 10 -8 centimeter and characteristically remains undivided in chemical reactions except for limited removal, transfer, or exchange of certain electrons.
Bohr's model describes an atom as small, with a positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus
The electron cloud model best describes the organization of electrons around the nucleus of an atom.
The electron cloud model best describes the organization of electrons around the nucleus of an atom.
The nucleus of an atom is made of 'Protons' and 'Neutrons'. The nucleus of an atom is then surrounded by 'Electrons'.
