10 While a student is holding a piece of metal in her hand, her hand gets colder. What happens to the temperature of the metal? * m (6 Points) A. The piece of metal will get warmer because some thermal energy is transferred from the metal to the student's hand. B. The piece of metal will get warmer because some thermal energy is transferred from the student's hand to the ON metal. C. The piece of metal will stay at the same temperature because an equal amount of thermal energy is exchanged between the student's hand and the metal. D. The piece of metal will stay at the same temperature because thermal energy is not transferred between the student's hand and the metal.

B

Explanation:

thermal energy is the energy between one object to another

h let me think

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
