According to the Modern Periodic Law, the properties of the elements are repeated after certain regular intervals when these elements are arranged in order of their increasing atomic numbers. Further an examination of the electronic configuration of the various elements clearly indicates that with a gradual increase in atomic number there occurs a repetition of similar outer electronic configurations after certain regular intervals. By correlating these two observations, we can say that, the cause of periodicity in properties is the repetition of similar outer electronic configurations at certain regular intervals. When we go across the period the no. of shells remains same but the number of electrons keep increasing .this result in more force of attraction among electrons and protons and thus atomic size decreases. But when we go down the group, the no. of valence electrons remains same but the no. of shells keep increasing.this result in less force of attraction. Therefore, atomic size increases.
What else can I help you with?
Peat and repeat was sitting in a tree peat fell out and who was left?
The victim will say, "Repeat," so then you repeat the question. It's a funny trick to try out on other people.
A crystal is always?
... composed of periodic repeat units, I suppose. The question isn't very well defined.
When do seasons repeat?
They are repeat in 1 day.
What are three things that repeat in a cyclic pattern?
1. The light that flashes on your phone when you get a message. 2. A heart- beat 3. A season or evaporation
Who discovered the atomic number?
The ability to weigh atoms came about by an observation from an Italian chemist named Amadeo Avogadro.Pioneers in the field of atomic weights of chemical elements were John Dalton and Jons Jakob Berzelius.
What is the difference between periodic and non-periodic changes changes?
Periodic changes are those changes that repeat themselves at frequent intervals of time. Non periodic changes are those changes that do not repeat themselves at regular intervals of time
Are the properties of elements that are based on electron configurations unpredictable and repeat in periodic patterns?
Yes, the properties of elements based on electron configurations are predictable and repeat in periodic patterns. This is known as the periodic law, where elements are arranged in the periodic table according to their increasing atomic number and similar chemical properties recur at regular intervals.
When mendeleev made his arrangement of the elements in a table he found that elements with fell into groups on the table.?
Yes, Mendeleev noticed that elements with similar properties tended to repeat at regular intervals when arranged by atomic mass, forming groups or columns in his periodic table. This led him to predict the properties of undiscovered elements and leave gaps in the table for them.
Is the signal with zero frequency a periodic signal?
No, because for a signal to become periodic it must repeat itself in regular intervals of its time period.A 0 Hz signal has a time period equal to infinity , so technically the signal can never complete a full cycle by reaching infinity let alone repeat itself, since the signal is unable to repeat itself in regular intervals its not periodic.
Does a periodic motion repeat at regular time intervals?
Yes, a periodic motion repeats at regular time intervals. This means that the motion follows a pattern that recurs consistently over time. Examples of periodic motions include the swinging of a pendulum or the vibrations of a guitar string.
Form of french verse in which lines are repeated at regular intervals?
The form of French verse in which lines are repeated at regular intervals is called a villanelle. This structured poetic form is made up of 19 lines with a specific rhyme scheme and refrains that repeat throughout the poem.
What is it called when it has repeat pattern?
A repeat pattern is often referred to as a "repeating motif" or "repetitive pattern." In design and art, it can also be called a "pattern repeat." This term describes a sequence of shapes, colors, or elements that recur at regular intervals, creating visual rhythm and consistency.
Why do elements repeat?
Element do not repeat, each element is Unique.
What chemical have similar property to magnesium?
the elements that lie in the group in which magnesium lies will repeat the properties of magnesium.
What does Mendeleev's periodic law stated?
physical and chemical properties are the fundamental property of d Atomic Mass.This law was stated in d year 1869.
What are periodic-waves?
A series of regular timed disturbances in a medium.
How can you tell if a pattern you see is the result of earth's revolution or earth's rotation?
Observations that repeat at regular intervals of nearly 24 hours ... nearly the same time every day or night ... are the result of earth's axial rotation. Observations that repeat at regular intervals of roughly one year are the result of earth's orbital revolution.
