As you move from left to right across the periodic table, each element has one more ________ than the element before it. questio
mylen [45]
The answer should be 2) electrons. 

The elements in the periodic table are arranged by increasing atomic number, which is also the number of protons in an element. For example, Carbon has 6 protons, it is the sixth element on the table. While Nitrogen, which has 7 protons, is after Carbon. 

In atoms, the number of protons equals to the number of electrons too, if the number of electrons does not equal to the number of protons, the substance is no longer atom, but ion. So, the answer to this is 2) electrons, as the elements on the table is arranged according to increasing atomic numbers.

how does resistance change with temperature? is there more resistance or less resistance at higher temperatures?
timofeeve [1]

The resistance has a linear relationship with temperature because it increases as temperatures increases.

<h3>What is temperature?</h3>

Temperature refers to the activity (motion or thermal energy) in the atoms that form molecules.

The resistance of an electric conductor increases as the temperature increases since the thermal energy of subatomic electrons also increases.

In conclusion, the resistance has a linear relationship with temperature because it increases as temperatures increases.

vichka [17]

Answer:

C. Chemical Energy

Explanation:

The energy that stored in the substance or in compounds is called chemical energy which released when the substance reacts.

A substance is made up of atoms and molecules and chemical energy is present in those atoms or molecules. When a chemical reaction takes place, these energy released from atoms and molecules.

Chemical energy can be released in the form of  thermal energy (heat) and mechanical energy (working ability).

Hence, the correct answer is "C. Chemical Energy".
