What is the group of elements with the same number of valence electrons?
Elements in the same group on the periodic table have the same number of valence electrons. Valence electrons are the electrons in the outermost energy level of an atom and determine an element's chemical properties.
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
What is the number of valence electrons in alkaline earth metals?
Alkaline earth metals have 2 valence electrons.
Elements that have an intermediate number of valence electrons will behave more like metals if they are?
Elements with an intermediate number of valence electrons will behave more like metals if they are on the left side of the periodic table, closer to the alkali metals. These elements tend to have low ionization energies and are more likely to lose electrons to form positive ions, exhibiting metallic characteristics such as conductivity and malleability.
How do you use the periodic table to recall the ionic charge of an alkali metal an alkaline earth metal or aluminum?
The ionic charge depends on the number of valence electrons. Alkali metals, alkaline earth metals and aluminium have 1, 2 and 3 valence electrons respectively and will hence form ions with +1, +2 and +3 charges respectively.

How many valence electrons do the elements of alkali metals have?
Valence electrons are the electrons present in the outermost shell of an atom.You can easily determine the number of valence electrons an atom can have by looking at its Group in the periodic table.For example, atoms in Groups 1 and 2 have 1 and 2 valence electrons, respectively.Atoms in Groups 13 and 18 have 3 and 8 valence electrons, respectively.
What is the number of valance electrons in atoms from alkali metals?
they have one valence electron. this is why they are so highly reactive and cannot be found pure in nature.
What is the number of valence electrons in alkaline earth metals?
Alkaline earth metals have 2 valence electrons.
Why will an alkali metal often combine with a halogen nonmetal to form a compound?
Well, the "happy" number in chemistry is eight. And alkali metals have one valence electron while halogens have seven so when they combine, the combination has eight valence electrons. This means it is full.
Do transition have higher melting point than alkaline and alkali metals?
Yes, transition metals generally have higher melting points compared to alkaline and alkali metals. This is because transition metals have a greater number of valence electrons and a stronger metallic bond, which requires more energy to break and transition from solid to liquid. In contrast, alkaline and alkali metals have fewer valence electrons and weaker metallic bonds, resulting in lower melting points.
What element had the fewest valence electrons?
hydrogenhydrogen------------------------------------------------------Put the following elements in order, with the element having the most valence electrons at the top of your list and the element with the fewest valence electrons at the bottom.NEONCHLORINESULFURNITROGENSILICONBORONCALCIUMSODIUM
