Elements are the simplest complete chemical substances. Each element corresponds to a single entry on the periodic table. An element is a material that consists of a single type of atom. Each atom type contains the same number of protons. … Elements cannot be divided into smaller units without large amounts of energy.
What is the most important characteristic of an element?
The single most important characteristic of an atom is its atomic number (usually denoted by the letter Z) which is defined as the number of units of positive charge (protons) in the nucleus. For example if an atom has a Z of 6 it is carbon while a Z of 92 corresponds to uranium.

What are the characteristics that make elements different from compounds?
Element. Elements and compounds are pure chemical substances found in nature. The difference between an element and a compound is that an element is a substance made of same type of atoms whereas a compound is made of different elements in definite proportions.

| Contain only one nucleus with numerous electrons protons and neutrons. | Atoms have the same numbers of protons. |
What is element in science definition?
chemical element also called element any substance that cannot be decomposed into simpler substances by ordinary chemical processes. Elements are the fundamental materials of which all matter is composed.
What is the major characteristic of the first and last elements in the period of the periodic table?
The main characteristics of the last element in the period of the periodic table are inert and stable. It is because the valence orbits of the last elements in the period of the periodic table are entirely filled.
What is the main characteristic of the last elements in the periods of the periodic table?
(a) The main characteristic of the last elements in the periods of the periodic table is that they all have 8 valence electrons in their atoms except helium. Such elements are known as noble gases that have a stable electronic configuration.
What is the major characteristic of the first element in the period of periodic table what is the general name of such element?
The first elements in the periods of the periodic table have 1 valence electron. Such elements are called alkali metals.
