Both are important; which is MORE important depends on what you're trying to do. If you're looking for electricity, then the electrons are more important. If you're looking for something material, then the nucleus is more important.
The distance of the electron cloud from the nucleus affects the atom's stability. When the electron cloud is closer to the nucleus, the atom is more stable. This is because the positively charged nucleus and negatively charged electrons are closer together, creating a stronger attraction. Conversely, if the electron cloud is further from the nucleus, the atom is less stable as the attraction between the nucleus and electrons is weaker.
In atoms. More specifically, they orbit the nucleus of an atom, in the aptly name electron cloud. Or electron shell.
The nucleus is significantly more dense than the electron cloud. The nucleus contains most of the mass of an atom, while the electron cloud occupies a much larger volume with a very low density.
No, it is not. Almost all of the mass of an atom is located in the nucleus. The proton, that carrier of the positive electrical charge, is some 1836 times more massive that the negatively charged electron that it attracts to "build" an atom. If we take a look, we'll find that in a simple hydrogen-1 atom, a single proton is in the nucleus and a lone electron makes up the electron cloud. And the nucleus is about 1836 times more massive than the "rest" of the atom. In a helium-4 atom, two protons and two neutrons form the nucleus and a pair of electrons form the electron cloud. In this case, the nucleus is about 7,444 times as massive as the electrons. As we move up the periodic table, the figure gets even more lopsided.
Yes, when an effective nuclear charge increases it does pull the electrons closer to the nucleus. An electron is a negatively charged part of an atom.
Electron is a negative sub atomic particle which revolves round the nucleus.
Electrons that are further away from the nucleus have a greater attraction because the positive and negative charges are stronger than innermost electrons
As the orbit of the electron increases, the electron's energy also increases. Electrons in higher energy orbits are farther from the nucleus and have more potential energy. Conversely, electrons in lower energy orbits are closer to the nucleus and have less energy.
The protons and neutrons found in the nucleus are responsible for the majority of the atom mass while the much smaller electrons orbit the nucleus.
No. The greater distance from the nucleus the more energy an electron has.
in the third shell, an electron has more energy and is further from the nucleus
Electrons are found in the outer regions of an atom, in what is called the electron cloud, around and outside the nucleus of the atom. This region has areas where electrons are more likely to be at any time, and these are called orbitals. There are various shaped orbitals.The closer an electron is to the nucleus, the more energy it would take to escape from the atom. The outermost electrons of an atom can be more readily shed or gained, and if this is done, the atom has a positive or negative charge because it has more or less protons than electrons, and is called an ion.Electrons are subatomic particles that orbit the nucleus of and atom and carry a negative electric charge they are also responsible for chemical changes during chemical reactions.
