Aluminium also known as Aluminum is found in group 3 period 3.
argon
they are found as element because in group 1 they react
The largest element in a Period (row) will be on the right of that Period (i.e. an inert gas). The largest element in a Group (column) will be at the bottom of that group. Examples; Helium is larger than Hydrogen (Period 1) Krypton is larger than Potassium (Period 3) Francium is larger than Lithium (Group 1) Ununquadium is larger than Carbon (Group 3)
Hydrogen is the least massive element. It is found in group 1, period 1 on the periodic table.
Hydrogen is placed in group-1 and period-1 in the periodic table as hydrogen has only one electron.
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
7th period because atomic size down the group increases. And Alkali Earth metals are found only in Group 1. The element is in Group 1 and period 7
1 bill
there is no element found in such a place because that spot doesn't exist. there is a period 4-7 but not 1-3 for group 6. that particular spot is open and doesn't include any elements
element K, or potassium
Chromium is the element in period 4 and group 6.
they are found as element because in group 1 they react
When the element moves from group 18 to group 1, it moves to a new period. Each period has a one more electron shell than the previous. The group 1 element has one more electron shell than the group 18 element; hence, it's atomic radius is greater.
Sodium (Na), element number 11.
The largest element in a Period (row) will be on the right of that Period (i.e. an inert gas). The largest element in a Group (column) will be at the bottom of that group. Examples; Helium is larger than Hydrogen (Period 1) Krypton is larger than Potassium (Period 3) Francium is larger than Lithium (Group 1) Ununquadium is larger than Carbon (Group 3)
Helium is the element that is placed in period 1 and group 18 of the periodic table. It is inert in nature and hence stable.
Hydrogen is the least massive element. It is found in group 1, period 1 on the periodic table.
