What is an element with a single electron in its highest energy level is probably what type of metal?
An element with a single electron in its highest energy level is likely an alkali metal. Alkali metals like lithium, sodium, and potassium have one electron in their outer energy level, making them highly reactive and likely to form ionic bonds.
How does the reactivity of an alkaline earth metal compare with that of alkali metal in the same period?
Alkaline earth metals are less reactive than alkali metals in the same period because they have higher ionization energies and are less likely to lose electrons. Alkali metals readily lose their outermost electron to form a +1 charge, whereas alkaline earth metals require more energy to lose their outermost two electrons to form a +2 charge.
How many energy levels are there in boron?
There are two energy levles in a Boron! :) Happy to help!
Electrons can only absorb photons that have energy equal to what?
Electrons can only absorb photons that have energy equal to the energy difference between two allowed energy levels in the atom or molecule.
If x stands for a metal how can you tell from the following formulas xcl and xcl2 which compound contains an alkali metal and which contains an alkaline earth metal?
In the formulas xCl and xCl2, the subscript "2" in xCl2 indicates that the compound contains a divalent metal, which is characteristic of alkaline earth metals. Alkali metals typically form compounds with a 1+ charge, so xCl would likely contain an alkali metal. Alkali metals are found in Group 1 of the periodic table, while alkaline earth metals are found in Group 2.
What alkali earth metal has electrons in exactly three energy levels?
Calcium is the alkaline earth metal that has electrons in exactly three energy levels. Its electron configuration is [Ar] 4s2, and it has two electrons in the 4s orbital and a total of three energy levels.
What is the alkali metal with two electrons in its plus 1 ion?
This alkali metal is lithium (Li).
Is titanium an alkali metal?
No it's not an alkali metal the alkali metal group is in group one and two
Why do the alkali metal have lower ionization energies than the alkaline earth metals?
Alkali gases only have 1 electron needing to be removed to reach a stable noble gas configuration. Alkaline earths have two electrons. Alkali metals thus have the lower ionization energy of the two groups.
What is an element with a single electron in its highest energy level is probably what type of metal?
An element with a single electron in its highest energy level is likely an alkali metal. Alkali metals like lithium, sodium, and potassium have one electron in their outer energy level, making them highly reactive and likely to form ionic bonds.
Alkali metal and alkaline earth metal have how many ionization energies?
Alkali metals (group 1 elements) have one valence electron. Hence have one ionization energy Alkaline earth metals (group 2 elements) have two valence electron. Hence have two ionization energy
What are two kinds of metal?
Metal (music) - doom and thrash Metal (element) - uranium and gold Metal (type of element) - alkali and transition
What is the name of alkali metal in period 3?
Calcium. The first two are beryllium and magnesium.
Is zinc an alkali metal or an alkaline earth metal?
no, alkaline earth metals are only in group 2 on the periodic table. nickel is a transitional metal
Table salt and sodium fluoride in toothpaste contain elements in what two families?
Table salt is NaCl: sodium is an alkali metal, chlorine is a halogen. Sodium fluoride: sodium is an alkali metal, fluorine is a halogen.
How does the reactivity of an alkaline earth metal compare with that of alkali metal in the same period?
Alkaline earth metals are less reactive than alkali metals in the same period because they have higher ionization energies and are less likely to lose electrons. Alkali metals readily lose their outermost electron to form a +1 charge, whereas alkaline earth metals require more energy to lose their outermost two electrons to form a +2 charge.
What alkali metal is liquid at 30 degrees Celsius?
They are soft, and generally can be cut with a knife, like cold butter.
