Elements are unique arrangements of subatomic particles that have a characteristic atomic structure and predictable chemical properties.

An element is composed of atoms that have the same atomic number. There are 118 elements that have been identified in which the lightest chemical elements are hydrogen and helium. Many elements have their isotopes. Every element have its unique arrangement.

the movement of aircraft through clouds can even cause lightning strikes. a single lightning event is a "flash", which is a complex, multi-stage explosively ejected.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
