What are three atoms that have eight valence electrons?
Three atoms that have eight valence electrons are oxygen, neon, and argon. These atoms have a full outer electron shell, making them stable and less likely to form chemical bonds.
How does boron's position in the periodic table hint that it is stable when bonded to only three atoms?
Boron tends to form molecules in which it is surrounded by only six valence electrons. Boron only has three valence electrons, and fluorine already has seven of the eight electrons it needs to fulfill its octet to be stable. Hope it helps!
Which of the following statements are true about whether atoms tend to gain or lose electrons?
Atoms with eight valence electrons usually do not gain or lose electrons. Atoms with one, two, or three valence electrons will lose electrons.
What is the number of electrons needed for stability in the groups of the periodic table?
They r noble gases which have stable valance shell and grotp no. 18
Why would some atoms share more than one pair of electrons?
Atoms are always trying to get a full valence shell (outer shell of electrons) to make themselves stable. Hydrogen and Helium only need two electrons to do this, but the other elements need eight electrons in their valence shell. Atoms try to accomplish this in the easiest way possible, using single bonds. Sometimes, though, this doesn't work. A common example of double bonding is carbon dioxide. Carbon has four electrons in its valence shell and wants to have eight. That means it wants other atoms to share four electrons with it so it can fill its shell. The two oxygen atoms that it bonds to when it becomes carbon dioxide have six electrons in their valence shell and want eight. That means they want to share two electrons each with another atom so they can have eight electrons in their valence shell and be "full". The atoms work together, sharing electrons to fill each other's valence shells, and each of the two oxygens form a double bond with carbon. The carbon atom gets two electrons from each oxygen (four total) to add to its own four to make a total of eight electrons (a full valence shell). Each oxygen gets two electrons from the carbon atom to add to its own six, making a total of eight electrons (a full valence shell). Basically, atoms share more than one pair of electrons in double or triple bonds because it's the best way for them to fill their valence shell.
Most atoms need eight valence electrons to be stable is called what?
Octet Rule!
What are three atoms that have eight valence electrons?
Three atoms that have eight valence electrons are oxygen, neon, and argon. These atoms have a full outer electron shell, making them stable and less likely to form chemical bonds.
How many valence electrons do most atoms need to have a complete outer Shell and be happy?
Most atoms need eight valence electrons to have a complete outer shell and achieve a stable, "happy" state, a concept known as the octet rule. However, there are exceptions, such as hydrogen and helium, which are stable with just two valence electrons. Atoms tend to gain, lose, or share electrons to reach this stable configuration.
Atoms with eight valence electrons form compounds easily?
Atoms with eight valence electrons are considered to be stable because they have a full outer electron shell, following the octet rule. These atoms are less likely to react with other atoms to form compounds, as they already have a complete electron configuration.
Are having eight valence electrons makes atoms very reactive?
No, eight valence electrons completely fills the valence band and makes the atom inert. The most reactive atoms have either one valence electron or seven valence electrons.
What predicts that atoms will react with each other to become more stable by filling their valence shells with eight electrons?
the octet rule does
How many more valence electrons does oxtyen need to have a full outer valence shell?
Oxygen has six valence electrons and requires two additional electrons to achieve a full outer valence shell, which is complete with eight electrons. This is in accordance with the octet rule, which states that atoms tend to gain, lose, or share electrons to attain a stable configuration of eight electrons in their outer shell.
When an atom has eight valence electrons it has a stable arrangement called what?
stable electronic configuration
What rule says atoms need to have 8 valence electrons?
The octet rule states that atoms tend to gain, lose, or share electrons in order to have a full outer shell of 8 electrons, which is a stable configuration. This is known as the octet rule because it applies to the first 20 elements in the periodic table, which aim to achieve a full valence shell similar to the noble gases.
How does boron's position in the periodic table hint that it is stable when bonded to only three atoms?
Boron tends to form molecules in which it is surrounded by only six valence electrons. Boron only has three valence electrons, and fluorine already has seven of the eight electrons it needs to fulfill its octet to be stable. Hope it helps!
How does an atom keep its charge?
An atom's charge changes when it gains or loses electrons. Atoms naturally tend to lose or gain electrons to level out at eight valence electrons (valence electrons are electrons in the outermost energy level), so the only atoms that keep their charge are ions with eight valence electrons or the Noble Gases, atoms on the far right of the periodic table that have eigth valence electrons and a nuetral charge.
When atoms end up with eight or zero valence electrons how are they different from they were before?
they become stable as they have completely filled outermost valence shell and if they have no electron in their outermost shell they become non reactive.
