Answer: cations
Explanation:
Metals are defined as the elements which loose electrons to attain stable electronic configuration. If an atom looses electrons, it leads to the formation of positive ions known as cations.
For Example: Sodium looses 1 electron to form ions.
Non-metals are defined as the elements which gain electrons to attain stable electronic configuration. If an atom gains electrons, it leads to the formation of negative ions known as anions.
For Example: Fluorine gains 1 electron to form ions.
Answer:
cations
Explanation:
metals are made of postively charged ions
Answer: As an object falls its potential energy decreases, while its kinetic energy increases. The decrease in potential energy is exactly equal to the increase in kinetic energy.
Explanation:
Answer: A.
Explanation:
Answer:
Did anyone get the answer?
Explanation:
The three similarities are hydrogen is produces, metal floats and move around the water, and metal disappeared. The difference is potassium is more reactive than lithium.
When metal reacts with water, hydrogen and metal hydroxide is produced.
Potassium is more reactive than lithium.
Alkali metals are also reactive with water.
The metal self ignites.
Thus, the three similarities are hydrogen is produces, metal floats and move around the water, and metal disappeared. The difference is potassium is more reactive than lithium.
