Largest element in a row and largest element in a column?
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)
What is the number of atoms in an element?
The number of atoms in an element depends on WHAT element AND how much of that element.
Are atoms with the same atomic number atoms of the same element?
yes. Isotopes of an element have the same number of protons, thus electorns, thus the same chemical properties. Where isotpes differ is in the number of neutrons. Consider hydrogen, atomic number 1, atomic weight 1, 1 proton, 1 electron vs duterium, atomic number 1 atomic weight 2, 1 proton, 1 electron, 1 neutron. H2O = water D2O = heavy water
What element is the 3rd element?
lithium is the third element. It is placed in group-1
What is the most reactive element in group 1A?
If I recall correctly, it's because they don't have any electrons in their atoms. Atoms react in order to get a full set of 8 electrons, and the less electrons an atom has, the more likely they are to react.
Which element has the largest size of atoms?
Atomic radii have not been measured or calculated based on theoretical principles for all of the elements. However, based on the information available in the wikipedia tables of atomic radii it would appear that the largest atom will prove to be that of francium.
Why do atoms of each element have 1 outer-level electron?
They don't. Of the main group, or representative elements, group 1 elements are the only ones whose atoms have only 1 electron in their outermost energy levels.
Largest element in a row and largest element in a column?
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)
What is the largest element of Period 3 on the Periodic table?
Sodium has the largest atomic size in the third period.
The alkaline earth element having the largest atomic radius is found in period?
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
What is the number of atoms in an element?
The number of atoms in an element depends on WHAT element AND how much of that element.
What element has only 10 atoms?
Considering that (1) atom = (1) element, the answer is zero.
What is the definition of group?
GroupNoun:1) Any number of entities (members) considered as a unit2) (Chemistry): two or more atoms bound together as a single unit and forming part of a molecule3) A set that is closed, associative, has an identity element and every element has an inverseVerb:1) Arrange into group or groups"Can you group these shapes together?"2) Form a group or group together
How is the number of atoms of a specific element in a compound denoted by?
The subscript to the left of the element symbol (unless it doesn't have a subscript; then the number of of atoms in the element is 1)
How many atoms of a Group 17 element would be needed to react with one atom of a Group 2 element Explain.?
Two of them. A group 2 element has two valency electrons whereas those in group 17 have 7. The latter need one electron to make an ionic bond so two of them can react with a single group 2 element.
What is the identity element of the quaternion group?
If you mean in the group {1, -1, i, -i, j, -j, k, -k}, the identity element is 1.
Which element is the first element in group 1?
If we look at the periodic table, we can see that the first element in Group I is Hydrogen.
