- happening; natural event; occurrence; occurrent (an event that happens)
- migration (the periodic passage of groups of animals (especially birds or fishes) from one region to another for feeding or breeding)
What is nature of elements in periodic table?
The “periodic” nature of chemical properties that Mendeleev had discovered is related to the electron configuration of the atoms of the elements. In other words, the way in which an atom’s electrons are arranged around its nucleus affects the properties of the atom. Each shell has a limited capacity for electrons.
What are the nature of elements?
Elements are substances that cannot be broken down into simpler things by chemical means. Elements of nature include: Hydrogen (H), with an atomic number of 1. This element gave rise to all others and accounts for 75% of the universe’s mass.
How many elements of nature are there?
Of the 118 elements that have been discovered, there are 90 elements that occur in nature in appreciable amounts. Depending who you ask, there are another 4 or 8 elements that occur in nature as a result of radioactive decay of heavier elements. So, the grand total of natural elements is 94 or 98.
What are periodic events give two examples?
Examples of periodic motion include a rocking chair, swing, tuning fork, and a pendulum. A satellite orbiting our planet and a mass bouncing on a spring are also examples of periodic motion.
What is periodic event in physics?
Events that take place after regular interval of time are called periodic event.
How do atoms exist in nature?
Atoms exist in nature in three forms – independently, molecules or ions. Atom is smallest unit of element. They are made up of protons, neutrons and electrons. Therefore, they either exist in form of combination as molecules or they exist in stable form as ions.
How do elements form in nature?
Stars create new elements in their cores by squeezing elements together in a process called nuclear fusion. First, stars fuse hydrogen atoms into helium. Helium atoms then fuse to create beryllium, and so on, until fusion in the star’s core has created every element up to iron.
What are the 3 elements of nature?
The three elements of nature, according to Heraclitus: earth, water, and fire, aka the three element theory.

What are periodic waves?
A periodic wave is one that repeats as a function of both time and position and can be described by its amplitude, frequency, wavelength, speed, and energy.
