What else can I help you with?
How many electrons are needed to complet the fourth row?
18 electrons are needed to complete the fourth row of the periodic table. This row includes the elements from potassium (K) to krypton (Kr), with a total of 18 elements in the row. Each element in this row has electrons filling up the 4th energy level, which can hold a maximum of 18 electrons.
How many outer orbital electrons are found in an atom of radium?
Two electrons in the outer shell of radium.
What does it mean when two or more elements are in the same row on the periodic table?
It means that the elements have same number of shells. Period determines the number of shells of an element.
What does the position of a particular element in a horizontal row in the periodic table tell you?
The position of an element in a horizontal row, or period, in the periodic table tells you the number of electron energy levels that element's atoms have. As you move from left to right across a period, the number of electrons in the outer energy level of the atoms increases by one.
Name the metalloid with 3 energy levels occupied by electrons?
Whatever row the element is in on the periodic table is the energy level, so the answer would be the metalloid in the third row, which is silicon (Si).
What determines where one row ends and another begins in the periodic table?
The row in the periodic table is determined by the principal quantum number (n) of the element's electrons, which represents the energy level or shell that the electrons occupy. Each row corresponds to a different principal quantum number, with the first row corresponding to n=1, the second row to n=2, and so on.
How are the element within a row different?
They have different numbers of valence electrons.
How many electrons are needed to complet the fourth row?
18 electrons are needed to complete the fourth row of the periodic table. This row includes the elements from potassium (K) to krypton (Kr), with a total of 18 elements in the row. Each element in this row has electrons filling up the 4th energy level, which can hold a maximum of 18 electrons.
How are the elements wth in a row different?
As you move across the periodic table from left to right, the elements within a given row have their electrons in the same energy level (given by the number of the row they are in). They way they differ is by the number of electrons. Moving from left to right, the number of electrons increase.
What do all the element in one row of the periodic table have in common?
they all have the same number of core electrons
What feature is the same for each element in a row in the periodic table?
Electrons are being added to the same energy level.
What do you call elements in a row on the periodic table?
Elements in a row on the periodic table are called periods. They represent the number of electron shells an element's atoms have. Each period corresponds to the energy level of the electrons in an element's atoms.
What is row on the periodic table called what do they have in common?
The row is called the period. Each element in the same period has the outermost electrons in the same shell (energy level). For example, the elements in the 3rd period all have the outermost electrons in the 3rd shell.
How many shells are in an element in the sixth row of the periodic table?
An element in the sixth row of the periodic table, such as cesium (Cs) or barium (Ba), will have 6 electron shells. The sixth row corresponds to the sixth energy level or principal quantum number, which determines the number of electron shells in an atom.
How many outer orbital electrons are found in an atom of radium?
Two electrons in the outer shell of radium.
What does it mean when two or more elements are in the same row on the periodic table?
It means that the elements have same number of shells. Period determines the number of shells of an element.
What does the position of a particular element in a horizontal row in the periodic table tell you?
The position of an element in a horizontal row, or period, in the periodic table tells you the number of electron energy levels that element's atoms have. As you move from left to right across a period, the number of electrons in the outer energy level of the atoms increases by one.
