When all group IIA lose their valence electrons the remaining electrons configurations are the same as for what family of elements?
When group IIA elements lose their valence electrons, they form cations with a +2 charge and have the same electron configuration as the nearest noble gas in the periodic table, which is group VIIIA (noble gases).
Why electron affinity value of IIA group less than those if IIA?
The electron affinity values of Group IIA (alkaline earth metals) are generally lower than those of Group IIA (halogens) due to their electron configurations. Group IIA elements have a filled s subshell, making it energetically unfavorable to gain an additional electron, as they prefer to lose electrons to achieve a stable noble gas configuration. In contrast, Group IIA elements have higher electron affinity values because they have a strong tendency to gain an electron to complete their p subshell, leading to greater stability. Thus, the difference in electron affinity reflects the distinct chemical behaviors and stability preferences of these groups.
What cation has 18 electrons and is in group IIA?
The cation with 18 electrons and in group IIA is calcium (Ca^2+). Calcium loses its two valence electrons to achieve a stable electron configuration similar to a noble gas.
What is the charge for elements in group IIA?
The charge for all elements in Group 2A is +2.
What is the trend in atomic size in the series of Group IIA elements Be through Ra?
The atomic size increases as you move down the Group IIA elements from Be to Ra. This trend is due to the increase in the number of electron shells as you move down the group, leading to greater atomic radius.
Which group contains an element that is liquid at stp ia iia ib or iib?
The ONLY liquid elements (at STP) areMercury, Hg, in group 12Bromine, Br, in group 17Notations like ia, iia, ib or iib are not commonly in use, maybe in older books or periodic tables.
What family does calcium belong to.?
Calcium is one of the alkaline earth metals in group 2 (or IIa) of the periodic table.
What does IIA do?
The Institute of Internal Auditors (IIA) is an international professional organization representing the internal auditing profession.
What are the elements in Group IIA on the periodic table?
The elements in Group IIA on the periodic table are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). These elements are alkaline earth metals and share similar chemical properties.
What is stage IIA of cervical cancer?
Stage IIA: Cancer has spread to the upper region of the vagina, but not to the lower one-third of the vagina
When all group IIA lose their valence electrons the remaining electrons configurations are the same as for what family of elements?
When group IIA elements lose their valence electrons, they form cations with a +2 charge and have the same electron configuration as the nearest noble gas in the periodic table, which is group VIIIA (noble gases).
What is the only liquid in the halide family?
If you think to halogens (not halides) bromine is a liquid.
What element is in the hailide family that is a liquid?
Bromine is a liquid.
How many men were in the IIA coastal boat crew?

How do IA and IIA differ the other Group A elements?
base in my experience.... because of the gravity of the earth...
What is the survival rate for stage IIa and IIb malignant melanoma patients?
Survival drops in stage IIa to about 65% at five years and is worse yet for stage IIb at slightly over 50%.
