Hydrogen bond. Is the answer.

Answer: Hydrogen bond.

Explanation: Water is a polar covalent molecule in which two hydrogen atoms are bonded to central oxygen atom via single covalent bonds. So, metallic, nonpolar covalent or ionic choices are not correct. The only correct choice is hydrogen.

Hydrogen bonding is present in ice as we know that hydrogen bonding takes place when hydrogen is bonded to the more electron negative atoms(F, O or N). Density of ice decreases as the molecules are farther from each other due to the presence of hydrogen bonding. This hydrogen bonding breaks when ice melts to water and the molecules comes closer.

Atoms of metallic elements tend to...
lara31 [8.8K]

The answer is: lose electrons and form positive ions.

Most metals have strong metallic bond, because of strong electrostatic attractive force between valence electrons (metals usually have low ionization energy and lose electrons easy) and positively charged metal ions.

The ionization energy (Ei) is the minimum amount of energy required to remove the valence electron, when element lose electrons, oxidation number of element grows (oxidation process).

For example, magnesium has atomic number 12, which means it has 12 protons and 12 electrons. It lost two electrons to form magnesium cation (Mg²⁺) with stable electron configuration like closest noble gas neon (Ne) with 10 electrons.  

Electron configuration of magnesium ion: ₁₂Mg²⁺ 1s² 2s² 2p⁶.

What is a state function?
fredd [130]
Is a function defined for a system relating several state variables or state quantities that depends only on the current equilibrium thermodynamic state of the system[1] (e.g. gas, liquid, solid, crystal, or emulsion), not the path which the system took to reach its present state. A state function describes the equilibrium state of a system, thus also describing the type of system. For example, a state function could describe an atom or molecule in a gaseous, liquid, or solid form; a heterogeneous or homogeneous mixture; and the amounts of energy required to create such systems or change them into a different equilibrium state.

when particles of matter are in direct contact and movement occurs in the substance due to convection, thermal energy transfers
liq [111]

Thermal energy transfers in a solid state, due to convection, in metalic substances.

This is because the covalent bonds between the atoms are being broken and reformed again while the metal is experiencing stress. <em>covalent bonds store energy.  </em>
