What does ra stand for on the periodic table of element?
Ra stands for Radium. It is present in group-2.
Radium, the 88th element.
Radium (Ra) is the 88th element on the periodic table.
Radium (Ra) # 88th element in the periodic table.
Radium has the symbol Ra.
Ra is the symbol for the element radium.
The 88th element on the periodic table is radium. The symbol for radium is Ra. This element is radioactive and emits three types of radiation.
Next element in the periodic table ie Actinium.
The alkaline earth metals in the periodic table are in group 2. They would be Be, Mg, Ca, Sr, Ba and Ra.
Radium (Ra, #88).
This chemical element is radium (Ra).
Yes, it is. RA is Radium.
The group 2 of the periodic table of Mendeleev contain the following elements: Be, Mg, Ca, Sr, Ba, Ra.
Those elements that are also is group II of the periodic table, namely Be, Mg, Sr, Ba and Ra.
Ba has greater nuclear charge than than Ra due to difference in energy levels thus it has greater electrostatic attraction which makes it to have bigger ionisation energy
The atomic number of radium (Ra) is 88. The atomic weight of Ra is 226 grams per mole. See the Web Links to the left of this answer for a periodic table with more information about this element!
Radium is element number 88 with the symbol Ra. Radium is an alkaline earth metal in group 2 of the periodic table. Radium is radioactive and very toxic.
Radium has 88 protons.
Elements in the second group of periodic table are alkaline earth metals.They are Be,Mg,Ca,Sr,Ba and Ra.
(I believe that it would be-) Radium (Ra) 88 (Group (up and down) 2A, and period (across) 7 would give you radium.)
88 Ra (226) Radium 2+
In the periodic table of Mendeleev radium is in the second group (alkaline earth metals), period 7, atomic number 88; Ra ia a radioactive element, solid, rare in the nature.
group 2 is Be, Mg, Ca, Sr, Ba and Ra
Group-2 elements or alkaline earth metals(i.e.Be,Mg,Ca,Sr,Ba,Ra) makes up earth metals in periodic table
The elements in Group 2 of the Periodic Table (alkaline earth metals) are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).
The elements in the lower right part of the periodic table. Cs, Fr, Ra, Ba etc.
Any element in the 2A column of the periodic chart: Be, Mg, Ca, Sr, Ba, and Ra.
The alkaline earth metals are in Group 2 on the periodic table. They are beryllium, Be, magnesium, Mg, calcium, Ca, strontium, Sr, barium, Ba, radium, Ra. These are not to be confused with the alkali metals, which are in Group 1 on the periodic table.
Yes they do. The group goes Be, Mg, Ca, Sr, Ba, Ra
Group 2 on the periodic table. Be, Mg, Ca, Sr, Ba and Ra.
There are two columns (groups) on the Periodic Table that contain the word 'Alkali'. They are the first and second groups. The first group is the Alkali Metals. This group contains the elements Li, Na, K, Rb, Cs, Fr. The second group on the Periodic Table is the Alkaline Earth Metals. This group contains the elements Be, Mg, Ca, Sr, Ba, Ra.
What information does the organization of the periodic table tell you about how reactive an element may be?
The upper right part (example O, F, Cl) and the lower left part (example Cs, Fr, Ra) elements are morte reactive than other parts, but this is only a rule of thumb.
In a true periodic table, those two series would actually be inserted between Ba and Lu and between Ra and Lr. These elements have separate properties than others in the periodic table, and adding them directly in their place (instead of just separating them) would disrupt the classical group numbering system, make the periodic table ridiculously long, and just plain make it even harder to understand.
Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), and Radium (Ra). Period 2.
I think it's radium (Ra); but also barium has a similar empirical radius - 215 pm.
The group 2 of the periodic table contain Be, Mg, Ca, Sr, Ba, Ra.
Ra is radium
The alkaline earth elements Be, Mg, Ca, Sr, Ba, Ra have 2 valence electrons
A comparison is possible with beryllium and calcium.
The group 2 of the periodic table contain the alkali earth metals: Be, Ca, Mg, Sr, Ba, Ra.
The lanthanides are elements 57-71 and are inserted after barium (Ba) on the periodic table. The actinides are elements 89-103 and are inserted after radium (Ra) on the periodic table. The reason they are there is because of the filling of electron orbitals in the atoms of the elements. There are four known orbitals, the s, p, d, and f orbitals. The lanthanide and actinide blocks are the result of electrons being inserted into the… Read More

Be, Mg, Ca, Sr, Ba, Ra. All the elements in that column have properties similar to each other.
Group 1 of the periodic table of Mendeleev, alkaline metals: Li, Na, K, Cs, Rb, Fr (monovalent metals) Group 2 of the periodic table of Mendeleev, alkaline-earth metals: Be, Ca, Mg, Sr, Ba, Ra (bivalent metals)
Group 2 (IIA) - Alkaline earth metals: Be, Mg, Ca, Sr, Ba, Ra ns2
Alkali metals are in the group 1 of the periodic table: Li, N, K, Cs, Rb, Fr. Alkaline earth metals are in the group 2 of the periodic table:Be, Mg, Ca, Sr, Ba, Ra.
The chemical symbols (not periodic) of radium and polonium are Ra and Po.
Alkaline Earth Metals are the elements located in group/family 2, or the second column of the periodic table. They include Beryllium-Be, Magnesium-Mg, Calcium-Ca, Strontium-Sr, Barium-Ba, and Radium-Ra. They have 2 electrons in their outer shell making them very reactive, and are not found freely in nature.
The alkaline earth metals are a series of elements comprising Group 2 (IUPAC style) (Group IIA) of the periodic table: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra). This specific group in the periodic table owes its name to their oxides that simply give basic alkaline solutions.
There are 12 elements classified as metals in the Periodic Table of Elements. The alkali metals: • lithium (Li) • sodium (Na) • potassium (K) • rubidium (Rb) • caesium (Cs) • francium (Fr) And the alkaline earth metals: • barium (Ba) • beryllium (Be) • calcium (Ca) • magnesium (Mg) • radium (Ra) • strontium (Sr) ---- The list is not complete.
