How many electrons are in the first orbital closest to the nucleus?
two electrons
The closest orbital to the nucleus, called the 1s orbital, can hold up to two electrons. This orbital is equivalent to the innermost electron shell of the Bohr model of the atom. It is called the 1s orbital because it is spherical around the nucleus. The 1s orbital is always filled before any other orbital.
How many electrons can be held in the second orbit closest to the nucleus?
eight
Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on.
How many electrons each orbital can hold?
Each orbital can hold no more than two electrons. Two electrons in the same orbital must have opposite spins (the Pauli exclusion principle).
How many electrons can orbit the nucleus?
The closest orbital to the nucleus, called the 1s orbital, can hold up to two electrons.
How many electrons are in the first shell?
2
Electron shells
| Energy shell | Maximum number of electrons |
|---|---|
| First | 2 |
| Second | 8 |
| Third | 8 |
How many electrons can the first energy level hold?
For example, energy level I can hold a maximum of two electrons, and energy level II can hold a maximum of eight electrons. The maximum number depends on the number of orbitals at a given energy level. An orbital is a volume of space within an atom where an electron is most likely to be found.
How many electrons can be held in the third orbit?
eight electrons
The innermost shell is filled first. This shell can contain a maximum of two electrons. The second shell can hold a maximum of eight electrons. When this is filled, electrons go into the third shell, which also holds a maximum of eight electrons….Electron shells.
| Energy shell | Maximum number of electrons |
|---|---|
| First | 2 |
| Second | 8 |
| Third | 8 |
How many can each orbital hold?
2 electrons
Orbital: A region of space within an atom where an electron in a given subshell can be found. Any orbital can hold a maximum of 2 electrons with opposite spin.
How many electrons can the first shell hold?
How many electrons can the 3rd orbital hold?
The second shell can hold a maximum of eight electrons. When this is filled, electrons go into the third shell, which also holds a maximum of eight electrons….Electron shells.
| Energy shell | Maximum number of electrons |
|---|---|
| Third | 8 |
How many electrons can fit in the shell closest to the nucleus?
The shell closest to the nucleus, 1n, can hold two electrons, while the next shell, 2n, can hold eight, and the third shell, 3n, can hold up to eighteen. The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms.
How many electrons can m shell hold?
M-shell is the third energy level and can have a maximum of 8 electrons. The atomic number of an element is 20.
