He was credited with discovering the subatomic particle also known as the electron in 1897.
The two types of energy changes that occur are heat and light changes.
A glass jar sitting on a shelf.
If the shelf gets tipped the jar will slide off and convert to kinetic energy as gravity pulls it to land on the next level/floor
The appropriate answer is b. A metallic bond allows metals to conduct electricity. Metallic bonds are formed by atoms of metals in which the outer electrons of the atoms from a common electron cloud. In metallic bonding the atoms are not used up in the actual bond but are shared so they are free to move about to conduct electricity. Electrons in the other bond types are held in place in the molecule an are not free to move about so they cannot conduct electricity.
Answer:
A lot
Explanation:
- As you go down a group, the elements get larger in size
- All of the elements of the same group have the same # of valence electrons
- As you go to the right of a period, the # of electrons in the outermost shell increases
- The elements at the top right of the table have the highest electronegativity
- Groups 13 through 17 are nonmetals
- The last group contains noble gases
etc.
