What is the most common oxidation number for group three on the periodic table?
Generally third A group elements in the periodic table exhibit +3 oxidation state but Boron exhibit negative oxidation state also . The stable oxidation state of Tl is +1. It exhibit +3 also but +1 is more stable than +3. RGUKT IIIT NUZVID N091528
What shows the number of valence electrons in an atom pictorial fashion?
It's called the Periodic Table of the Elements, and it's very possibly the most useful thing in all of chemistry. The more you use it, the more comfortable you become with it, and the more it teaches you.
Is Gallium or Phosphorus more similar to Al?
Elements in a group generally have similar chemical properties because all the elements in that group have the same number of valence electrons, so Ga would be more similar to Al.
How do you use the valence electrons to tell what element it is?
The number of valence electrons in an atom determines its position in the periodic table and its chemical behavior. Elements in the same group have the same number of valence electrons. For example, all elements in Group 1 have 1 valence electron, and those in Group 17 have 7 valence electrons. By counting the number of valence electrons an atom has, you can determine its group and thus identify the element.
Why does carbon bond with so many different elements?
Carbon can bond with itself, and many other elements.
What elementscan exhibit more than one valence state Fe Cu Co NI?
actually all the elements listed can exhibit.
Are there any non metals?
No. Metal is a state of matter, not a chemical property. All elements are able to exhibit the metallic state at the right temperature and pressure. What we colloquially refer to as "metals" are those few elements that exhibit the metallic state at temperatures and pressures that are more common to us. But even hydrogen will become metallic at an estimated pressure of 25 GPa.
The elements in group 7A have one valence electron true or false?
A valence electron, or valence electrons, are found in all of the elements. A valence electron is an electron located on the out most shell of an element (the valence shell). Most elements will have more than one valence electron. Oxygen, or O, has six valence electrons because its outer shell consists of six electrons.
What is the most common oxidation number for group three on the periodic table?
Generally third A group elements in the periodic table exhibit +3 oxidation state but Boron exhibit negative oxidation state also . The stable oxidation state of Tl is +1. It exhibit +3 also but +1 is more stable than +3. RGUKT IIIT NUZVID N091528
How many valence electrons can an atom have?
That depends on the element in question. Atoms can have anywhere from 1 to 8 valence electrons. For the main group elements, Groups 1,2,13-18, the number of valence electrons are the number in the one's place in their group number, as follows: Group 1 Elements: 1 valence electron Group 2 Elements: 2 valence electrons Group 13 Elements: 3 valence electrons Group 14 Elements: 4 valence electrons Group 15 Elements: 5 valence electrons Group 16 Elements: 6 valence electrons Group 17 Elements: 7 valence electrons Group 18 Elements: 8 valence electrons The transition metals, Groups 3 - 12, are more complicated because they are adding d electrons, some of which behave like valence electrons, and many transition metals can have different numbers of valence electrons. For example manganese can have anywhere from 2 to 7 valence electrons.
What has more valence electrons than oxygen?
All halogen elements have 7 valence electrons (group 17): F, Cl, Br, I, At.
What causes an element to be reactive?
In the short form: elements are striving to completely fill valence shells of electrons to reach a quantumly stable energy state. They react to take electrons away from elements willing to give up electrons or share outer shell electrons with elements they aren't strong enough to steal from.
Why are elements stable on their own while others are more stable in compounds?
because of the valence toms

Why do group 17 elements typically form a negative ion?
You mean group VII of the periodic table? Group VII elements are known as halogens and they form -1 ions readily is as they only require 1 more electron to obtain full electronic configuration. They all lack 1 valence electron in their valence shells. Full electrion configuration means that there aren't any valence electrons.
How do you know the chemical reactivities of elements?
The farther the valence electron are from the nucleus, the more easily they can be lost therefore the more reactive the element is. i.e potassium would be more reactive than sodium (check their valence electrons)

because of the valence toms
