This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Ununquadium has seven electron shells.
The electron shell is an energy level represented as the distance of an electron from the nucleus of the atom

This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Elements in the same row, or period, of the periodic table fill up the same energy level as you move from left to right. This is because elements in the same period have the same number of electron shells.
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.
As you move across a period, elements have the same number of electron shells but different numbers of valence electrons. This leads to differences in reactivity and chemical properties across the period.
the rows of elements on the preiodic table are called the period. the period tells you the number of electron shells
The period of an element in the periodic table can be determined by the number of electron shells or energy levels that the element's atoms have. Each period on the periodic table corresponds to the number of electron shells occupied by the elements within that period.
Elements in the same period share the same number of electron shells. This means they have similar atomic sizes and properties because they have the same number of electron shells determining their size and behavior.
The elements on the periodic table are separated into periods based on the number of electron shells they have. Elements in the same period have the same number of electron shells, which influences their chemical properties and reactivity.
The element in group V of the periodic table with 3 electron shells is Phosphorus (P). Group V elements have 5 valence electrons and the number of electron shells corresponds to the period number on the periodic table, so a Group V element with 3 electron shells is in period 3.
The period of elements in the periodic table refers to the horizontal rows that categorize elements based on the number of electron shells they have. Each period corresponds to the number of electron shells an element's atoms possess, ranging from 1 to 7 as we move from left to right across the table.
Elements in the same period share the same number of electron shells, or energy levels. This means they have similar atomic sizes and exhibit similar chemical properties due to their outermost electron configuration.
The period on the periodic table refers to the horizontal rows that categorize elements based on the number of electron shells they have.
Each row in the table contains elements that have the same number of electron orbit shells. The first orbit, which is closest to the nucleus only has space for 2 electrons (no idea why, sorry). This is why only hydrogen (1 electron) and helium (2 electrons) are in the first row. The second row has the same inner shell, with 2 electrons and an outer shell with room for 8...and so on.
