Why do elements go from ground state to excited state?
Elements go from the ground state to the excited state if some form of energy is supplied. Otherwise, they stay in the ground state.
What is homeostasis failure?
Homeostasis is a relatively stable state of equilibrium or a tendency toward such a state between the different but interdependent elements or groups of elements of an organism, population, or group. Failure would be the failure of maintaining the equilibrium.
Which is negative oxidation state in 13 group elements?
Boron
What are the elements that have five electrons in the highest energy p sub level in their ground state called?
Halogens
What is the most common oxidation number for group three on the periodic table?
Generally third A group elements in the periodic table exhibit +3 oxidation state but Boron exhibit negative oxidation state also . The stable oxidation state of Tl is +1. It exhibit +3 also but +1 is more stable than +3. RGUKT IIIT NUZVID N091528
What do all the elements have in common in group 13?
ground-state level
Why do elements go from ground state to excited state?
Elements go from the ground state to the excited state if some form of energy is supplied. Otherwise, they stay in the ground state.
An atom of aluminum in ground state and an atom of gallium in the ground state have the same what?
Aluminium and gallium are members of the 13th group of the Mendeleev periodic table of elements.
What is the number of electrons in the valence shell of an atom of aluminum in the ground state?
2 valence electrons are in an aluminum atom in the ground state.
How many electrons will the elements have in the second group have on the periodic table?
There are 2 valence electrons (electrons in the outer shell) of group 2 elements in the ground (un-ionised or standard) state. This causes them to form +2 ions.
What does group 6A elements have compared to group 2A?
Group 2A * Known as Alkaline earth elements * All are metals * Occur only in compounds * React with oxygen in the general formula EO (where O is oxygen and E is Group 2A element)
Which atom in the ground state has only three electrons in the 3p sublevels?
There are several such elements. All of them are in group 13. Those elements are boron, aluminum, gallium, indium, and thallium.
What elements has a ground-state electron configuration different from the predicted one?
There are many elements among the transitional elements which has the electron configuration differed than predicted. Such element with the lowest atomic number is chromium.
Are group 1 or group 2 metals ever found in their elemental state?
All the chemical elements from group I and II are very reactive; it is impossible to found these elements in nature in elemental state.
What is homeostasis failure?
Homeostasis is a relatively stable state of equilibrium or a tendency toward such a state between the different but interdependent elements or groups of elements of an organism, population, or group. Failure would be the failure of maintaining the equilibrium.
Do all elements of a group have the same state of matter?
This not mandatory; see the halogens group.
Which is negative oxidation state in 13 group elements?
Boron
