What element is represented by the following electron configuration: 1s22s22p63s23p64s23d4 question 2 options: cr ca ge ar

For better representation, let me rewrite the electronic configuration:

1s²2s²2p⁶3s²3p⁶4s²3d⁴

The exponents represent the number of electrons in the designated subshell. Thus, the total number of electrons are:
# of electrons = 2+2+6+2+6+2+4 = 24

Assuming this is in neutral state, the element with an atomic number of 24 is Chromium. Thus, the answer is Cr.

In liquid water, hydrogen bonds are constantly being formed and broken as the water molecules slide past each other.

Explanation:

The breaking of these bonds is caused by the energy of motion (kinetic energy) of the water molecules due to the heat contained in the system.
