An atom has the electron configuration of 1s22s22p5 how many electrons are in that atom
notsponge [240]

Answer:

There are 9 electrons in this atom.

Explanation:

Electron configuration of this atom: 1s^2\, 2s^2\, 2p^5.

The electron orbitals of an atom are denoted as 1s, 2s, 2p, 3s, 3p, etc. At any given time, an electron in this atom is located in exactly one orbital.

The electron configuration of an atom gives the number of electrons in each orbitals of this atom.

For example, in this atom, the superscript "2" on the right of "1s" means that there are two electrons in the 1s\! orbital of this atom. Hence, 1s^2\, 2s^2\, 2p^5 would translate to:

  • The 1s orbital of this atom contains 2 electrons.
  • The 2s orbital of this atom contains 2 electrons.
  • The 2p orbitals of this atom contain 5 electrons.

Hence, there would be 2 + 2 + 5 = 9 electrons in total in this atom.

The density of silver is 10.5 g/cm3. A piece of silver that occupies a volume of 42.5 cm3 would have a mass of ________ g.
tia_tia [17]
M=D*V
D=10.5 g/cm³
V=42.5 cm³
m= 10.5 g/cm³ * 42.5 cm³ ≈ 446 g
m≈446 g
