Aluminium also known as Aluminum is found in group 3 period 3.
Lithium is in the first period of the periodic table. It is the first element in the alkali metal group.
Hydrogen is placed in group-1 and period-1 in the periodic table as hydrogen has only one electron.
The element in period 4 and Group 1 of the periodic table is potassium. It is a highly reactive metal that is soft enough to be cut with a knife. Potassium is essential for many biological processes and is found in compounds like potassium chloride and potassium hydroxide.
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
In, Sn, Sb, Te, I or Xe are all representative (main group) elements in the 5th period which is numbered on the left (1-7) and a "period" is the horizontal rows.
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
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
The correct element found in group 17 and period 5 is iodine (I). It is a non-metal element known for its distinct purple color and is commonly used in medicine and pharmaceuticals.
element K, or potassium
The element in the same group as lithium (Group 1) and the same period as iron (Period 4) is potassium.
The element in group 1 period 3 is sodium. Sodium has an atomic number of 11 and is a highly reactive metal.
Third period has 8 elements. They have 3 electron shells.
Lithium is in the first period of the periodic table. It is the first element in the alkali metal group.
Chromium is the element in period 4 and group 6.
On the periodic table group 4A is carbon, silicon, germanium, tin and lead. (aka "The Carbon Group")
Nitrogen is found in Group 15 and Period 2. Xenon is found in Group 18 and Period 5. Cesium is found in Group 1 and Period 6.
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
