What part of an atom exists in orbital surrounding the nucleus?
The electrons of an atom exist in orbitals surrounding the nucleus.
The part of an atom that exists in orbitals surrounding the nucleus is the electrons. Electrons are negatively charged particles that are arranged in specific energy levels or orbitals around the nucleus of an atom. They occupy regions of space around the nucleus known as electron shells or electron clouds.
The part of an atom that exists in the orbital surrounding the nucleus is the electron. Electrons are negatively charged particles that orbit the nucleus in energy levels or shells. These energy levels are organized into subshells (s, p, d, and f) which further divide into atomic orbitals (spherical, dumbbell-shaped, etc.) where electrons reside. To determine which part of an atom exists in the orbital surrounding the nucleus, one can refer to the atomic model and knowledge of electron configuration.
To find electron configuration, you can use the periodic table as a guide. Each element has a unique electron configuration that represents the arrangement of electrons in its shells and subshells. It is important to note that each energy level has a specific capacity to hold electrons. The first energy level (n=1) can accommodate a maximum of 2 electrons, the second energy level (n=2) can hold up to 8 electrons, and so forth.
For example, let's take the element carbon (C) with atomic number 6. To determine the electron configuration, you start by filling the energy levels and subshells in order of increasing energy. Carbon's electron configuration can be represented as 1s^2 2s^2 2p^2. This means that carbon has 2 electrons in the first energy level (1s orbital), 2 electrons in the second energy level (2s orbital), and 2 electrons in the second energy level (2p orbital).
Thus, in summary, the electrons are the particles that exist in the orbital surrounding the nucleus of an atom.
