How many electrons do alkali metal family have?
they all have a differnet number of electrons, but all have a charge of 1-
What is the number of valance electrons as you move right across a row or period in the periodic teale?
It depends on which group you are talking about. The number of valance electron normally increase by one as you move right across the table. when you get to the transition metals however, the valance electron will vary.
What is the number of valance electrons in oxygen?
six valence electrons
How many electrons do the alkali metals have in their outer energy shell?
If you are referring to the alkali metals of Group 1, such as sodium and potassium, the answer is no - in fact with a valence of 1 they are short 7 electrons in their outer level, which is why they react so readily (and violently) with the halogens, chlorine, fluorine and so on.
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 is the number of valence electrons for Alkali Earth Metals?
Alkali Earth metals have a single valence electron, and are found in the first group.
How can you tell if an element has more valance electrons than other element has from the periodic table?
The groups, or families of elements have the same number of valance electrons and this information can be found at the top of the periodic table. For instance; 1A represents the alkali metals and they all have a valance number of 1. Then go from the left to the right and look at the top of the table. 8A represents the farthest left family of elements, from top to bottom, the Nobel gasses. They have a full valance shell of 8 electrons.
How do the valence electron configurations of the alkali metals compare with others?
The valance electron configuration is the same in each at ns1 where n = the period number.
How do the valence electrons configurations of the alkali metals compare with each other?
The valance electron configuration is the same in each at ns1 where n = the period number.
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).
How many electrons do alkali metal family have?
they all have a differnet number of electrons, but all have a charge of 1-
How can the number of valence electrons be determined from the periodic table?
By looking at the group number you can tell how many valance electrons there are ex: Group 1= 1 valance electrons Group 2-12= 2 valance electrons Group 13= 3 valance electrons Group 14= 4 valance electrons Group 15= 5 valance electrons Group 16= 6 valance electrons Group 17= 7 valance electrons Group 18= 8 valance electrons
