Which form of energy increases in an object as you raise it higher off the ground? A. Electrical
B. Kinetic
C. Mechanical
D. Potential

D. Potential

Explanation:

Potential

Explanation:

Gravitational potential is the energy the object has of it's position of the earth's surface. When the object is lifted, work is done.  When work is done in raising the height of an object, energy is transferred as a gain in the gravitational potential energy of the object.

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.

c. orbital shape i hope this is correct
