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.

When do seasons repeat?
They are repeat in 1 day.
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.
Why do seasons repeat year after year?
No
A crystal is always?
... composed of periodic repeat units, I suppose. The question isn't very well defined.
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
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
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.
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.
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.
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.
In what way is the table of the elements periodic?
The Periodic Table is arranged in periods and groups; elements are placed in the ascending order of the atomic number. The law of periodicity from Mendeleev is respected.
In a periodic table a set of properties repeat from what?
B-Group to group
Why is atomic number considered to be the most appropriate parameter for the classification of elements?
The element's physical and chemical properties are based mainly on the number of protons they have, which is their atomic number. Elemental groups of properties seem to repeat every multiple of 8 proton number, so that is why the periodic table is arranged the way it is.
What law that states that the properties of elements repeat as a function of their atomic number?
boilis
How do you repeat things in RuneScape?
Many people in Runescape use autotypers to repeat a message at specific intervals. This is against the rules, but it's likely no one will care enough to report you. Also, if you are using quick chat, you can press F11 to repeat the last thing you said in quick chat.
Which algorithm is efficient for finding an element from a sorted list?
Basically you split the list in two, looking at the element in the middle of the list. If the list is in ascending order, and the element you are looking for is SMALLER than the element in the middle of the list, you repeat this procedure for the FIRST half of the list (again, splitting it in two); if it is LARGER, you repeat for the SECOND half of the list.
