The row of elements going left to right on the periodic table is called?
This row of chemical elements is a "period".
What is the term for a row of elements going from left to right on the periodic table?
Period
Going vertically across the periodic table is?
good ??????????????????????????????????????????????
The rows going across the periodic table is known as periods and contain elements with the same number of?
The rows going across the periodic table are known as periods and contain elements with the same number of electron shells.
What is the term for a row of elements going from up to down on the periodic table?
Group or family
How many elements on the periodic table of elements?
In the Periodic table of Elements There are 118 Elements 96 are metals The rest are non-metals Group 7= Halogens Group 8/0= Noble gases Going down group 1 and 2, elements become more reactive
Are columns of elements called periods?
No, columns of elements in the periodic table are called groups or families. Periods are the rows of elements that run horizontally across the table. Each period corresponds to the number of electron shells an element's atoms have.
Do the elements go from metals to nonmetal in the periodic table going from left to right?
Yes they do, with metaloids in between.
How do you figure the number of protons in a atom?
The number of protons in an element determines which element that atom is. The number of protons is given by the atomic number of that element. The element hydrogen is 1, helium is 2, lithium is 3, and so on.Any list of elements set down by atomic number will tell an investigator how many protons are in the nucleus of any given element on the list. In the periodic table of elements, by starting in the upper right corner and reading all the way across, and going down line by line, we can also find the number of protons in the nucleus of any given element. This is because in the periodic table of elements, there is still an order in which the elements are set down by atomic number starting with 1 and going to 2, 3, 4, and on up through the rest of the elements.
What is a periodic table what is the importance of using a periodic table?
The Periodic Table is a list of all ther known elements. This lisyt is in tabulated form. Taking any one column, the elements in that column are said to be in a group, and have similar reaction characteristics. Takinf any one row, the elements are said to be in a period.where the reaction characteristics change on going across the row.
What are periods and groups?
Elements in the periodic table are arranged in periods (rows) and groups (columns). Atomic number increases as you move across a row or period. The period number of an element signifies the highest unexcited energy level for an electron in that element. Elements within a group share several common properties. Groups are elements have the same outer electron arrangement. The outer electrons are called valence electrons.
What is the relationship between a period and a group in the periodic table?
A period in the periodic table refers to a horizontal row of elements that have the same number of electron shells. A group, on the other hand, refers to a vertical column of elements that have similar chemical properties due to having the same number of valence electrons. So, elements within the same period do not have similar properties, but elements within the same group do.
