What else can I help you with?
What element has only one valence electron give a symbol for each?
The alkali-group elements (group I of the periodic table) H, Li, Na, K, Rb, Cs, Fr in period 1 to 7 respectively.
Do group 1 metals contain reactive or unreactive elements and why?
Except hydrogen, elements in group 1 are very reactive at they can give away their only electron in their valence shell easily to be ionized.
Which element will give its electron away?
An element that is a metal is more likely to give away its electrons because metals tend to lose electrons in chemical reactions to achieve a stable electron configuration. Sodium and potassium are common examples of metals that readily give away electrons.
What metals react with other metals what happens to the valence electrons of the metal atoms?
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
When determining the formula for a compound it is important to know the valence numbers of each element. Suppose you want to-write a formula for a compound with these two elements?
To be stable it would need to be A2B (2 of element A would give a total of 6 valence electrons + the 1 element B would give a total of 8 electrons in the covalent bond. The bond is now stable and you have a compound.)
Where are strong electron doners on the table?
Metals are strong electron donors. They easily give their valence electrons.
Why does valence electron give up outermost energy easily?
The force of attraction between the atom's nucleus and its valence electrons are the least. Hence valence electrons are lost easily.
What is the relationship between an element's number of valence electrons and its reactivity?
When we say valence electron we mean the number of electron left it the outermost shell of element, valence electron can be positive of negetive. If an element need much electrons to be octet, that means that the element is not reactive than the one who will give out electrons, the the one who can give electrons much are less reactive than the one who can give a litle and the reaction will be normal as it is soppused to be, Eg lithium and berylium. Lithium is more reactive than berylium because lithuin has 1valence electron while berylium has 2....reactivity goes with the action of valence electron in an element
Does Francium give away electrons easily or hold on to them tightly?
Francium gives away electrons very easily due to its location in the alkali metal group, which makes its outer electron very loosely bound. This makes Francium highly reactive and likely to form ions by losing its single valence electron.
What element has only one valence electron give a symbol for each?
The alkali-group elements (group I of the periodic table) H, Li, Na, K, Rb, Cs, Fr in period 1 to 7 respectively.
Does hydrogen give up valence electrons eaisly?
Yes, it can stabilize by giving away its electron, the reactions between an acid and a metal can be explained by this behavior.
What is the electron diagram for SBr4?
Give the number of valence electrons for SBr4.
If an atom has one valence electron what will it form?
Since the element has only one valence electron, it will be very easy for it to lose it and form an ionic bond.
How many electrons does cesium have to give up to achieve a noble gas electron configuration?
Losing an electron cesium has a noble gas configuration.
How many electrons does pph3 give in the calculation of valence electron counts in the 18 electron rule?
In the calculation of valence electron counts using the 18-electron rule, phosphine (PH3) contributes 5 valence electrons. Since each hydrogen atom contributes 1 electron, the total valence electron count for PPh3 (Ph = phenyl group) would be 5 (from phosphorus) + 3x1 (from hydrogen) = 8 electrons.
Do group 1 metals contain reactive or unreactive elements and why?
Except hydrogen, elements in group 1 are very reactive at they can give away their only electron in their valence shell easily to be ionized.
What elements easily give up electrons?
Group 1 elements, such as lithium, sodium, and potassium, easily give up electrons because they have one electron in their outer shell and are highly reactive. Additionally, elements in Group 17, such as fluorine and chlorine, can also easily gain electrons.
