What is the different about the valence electrons for all elements in a group?
The valence electrons for elements in the same group stay the same, since the number of valence electrons corresponds to the group number.
When elements react what are given away?
electrons
How many elements contain the same number of outer electrons as sodium?
The number of elements that contain the same type of outer electrons as sodium is 11.
Why do elements in group 2 have the same properties?
All these elements have two valence electrons.
How the d-block group number relte to the number of outer s and d electrons?
The d-block elements have two electrons in their outermost s sublevels. The group 3 elements have one d electron in their outermost d sublevel, the group 4 elements have two d electrons, adding one additional d electron with each subsequent group until group 12 in which the elements have ten d electrons.
When determining an elements identity what is the most important subatomic part to examine?
Valance electrons!
Why do elements as a family or group share similar properties?
Because they have the same number of valence electrons and need the same number of electrons to fill their valence shells
How do you visually represent ionic bonds?
Show the sharing of electrons between the two elements.
What does the blocks represent?
For the elements in the s-block, the valence electrons are filled in the s orbital.
How many electrons represent a complete outermost energy level for elements heavier than boron?
14
What does the column in the periodic table stand for?
they represent elements. the elements in a given column (or group) have the same number of valence electrons and hence similar properties.
What important subatomic part determines the elements chemical properties?
Electrons.
The degree of polarity of a chemical bond in a molecule of a compound can be predicted by determining the difference in the?
electronegativity. this is the strength of the pull of electrons to the element, as opposed to the tendency of metallic elements to be electropostive, that is to give up electrons.
What effect does the nucleus have on atomic spectra of different elements?
Aside from determining how many electrons the atom has, the nucleus does not affect the spectra of that atom in any way.
What are elemental ions?
In the Periodic Table of elements you have elements, these elements represent neutral atoms of elements, ions are just like neutral atoms, the only difference is the have less or more electrons in the orbital. So Na is sodium atom and Na+ is sodium ion
In an periodic table dots around an elements symbol indicate the number of valence electrons in an atom?
yes, the number of dots represent the number of valence electrons in the periodic table.
What is the most important factor in an elements place in the periodic table?
Its elemental weight
