What does a period on the periodic table tell us?
Elements in the same period has same number of valence shells.There are 7 periods in Periodic Table.
What is the group of 17 elements is called?
A group of 17 elements is called a period in the periodic table. This period corresponds to the number of electron shells in an atom within that group. Elements in the same period have the same number of electron shells.
Are elements in a period arranged alphabetically?
NO!!! Elements in a Period are arranged by Atomic No. / Proton No. If we take PERIOD 1. . the two elements are Hydrogen and Helium, in that order. H**ydrogen , Hel**ium are NOT in alphabetical order.
How does the period number on the periodic table relate to the principle quantum number?
The period number on the periodic table indicates the value of the principal quantum number (n) for the elements in that row. Each period corresponds to the value of n for the outermost electron shell of the elements in that row. For example, elements in period 3 have electrons filling the third shell, which corresponds to the principal quantum number n=3.
What do all elements in the same period on the period the periodic table have in common?
A. They have the same number of protons.B. They have the same number of orbitals.C. They have the same number of electrons.D. They have the same number of neutrons.
How does the time period or number of variables effect correlation coefficient?
The time period may not affect the correlation coefficient at all. If looking at the correlation between the mass and volume of steel objects, time is totally irrelevant. The effect of the number of variables depends on whether or not the extra variables are related to ANY of the variables in the equation.
Which periods have the same number of elements?
Period 4 and period 5 of the periodic table have the same number of elements. There are 18 elements in each period. While some elements in period 4 are calcium, iron, and zinc, elements in period 5 are tin, antimony, and iodine.
What is special about a period on the periodic table?
all elements in a period all have the same amount of shells example: all elements in period 1 has only 1 shell all elements in period 2 has 2 shells so the period number is the same as the number of shells in that period
What does a period on the periodic table tell us?
Elements in the same period has same number of valence shells.There are 7 periods in Periodic Table.
What is the group of 17 elements is called?
A group of 17 elements is called a period in the periodic table. This period corresponds to the number of electron shells in an atom within that group. Elements in the same period have the same number of electron shells.
How are the elements in each period alike?
the number of protons
All of elements in period have same?
Number of Electrons.
Why are the elements ordered as they are in the period table?
Number of protons.
How does the number of valence electrons for elements across a period?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
What are the criteria used to placed an element under it is group and period?
Elements are placed in a group based on their similar chemical properties, such as reactivity and valence electrons. Elements are placed in a period based on the number of electron shells they have. Each period corresponds to the electron shell number of the elements in that period.
Row of elements in the periodic table?
the rows of elements on the preiodic table are called the period. the period tells you the number of electron shells
Are elements in a period arranged alphabetically?
NO!!! Elements in a Period are arranged by Atomic No. / Proton No. If we take PERIOD 1. . the two elements are Hydrogen and Helium, in that order. H**ydrogen , Hel**ium are NOT in alphabetical order.
