What does the group of the periodic have to do with reactivity?
The table was organized so that elements of similar properties are in the same group. What (partly) determines reactivity is the number of electrons an atom has in it's ground state. . Within the atom electrons are organized in shells. Atoms are stable when they have 8 electrons in their outer shell (for hydrogen and helium it is 2 electrons.) . Elements of: Group 18 have 8 electrons in their outer shells Group 17 have 7 electrons in their outer shells Group 16 have 6 electrons in their outer shells Group 15 have 5 electrons in their outer shells Group 14 have 4 electrons in their outer shells Group 13 have 3 electrons in their outer shells Groups 3-12 have varied number of electrons in their outer shells Group 2 have 2 electrons in their outer shells Group 1 have 1 electron in their outer shells
How many electrons does it have in its outer shell?
Antimony has 5 valence electrons.
Elements with complete outer shells?
Elements with complete outer shells have a full valence shell of electrons and are stable. This configuration is typically achieved by having eight electrons in the outer shell (known as the octet rule) or two electrons for the first shell. These elements are generally inert or have low reactivity due to their stable electron configuration.
If an atom has a stable number of electrons how can you tell?
If an atom has a stable number of electrons, it will have a full outer electron shell (valence shell). This full outer shell will typically have 2, 8, 18, or 32 electrons, depending on the period the atom is in. Atoms with full valence shells are considered stable because they are less likely to undergo chemical reactions to gain or lose electrons.
An atom is stable when it?
An atom is stable when the number of protons equals the number of electrons, creating a balanced electrical charge. Additionally, stable atoms have filled outer electron shells that follow the octet rule, meaning they have eight electrons in their outermost shell.
Do atoms whose outer elecron shells contain eight electrons tend to form ionic bonds in aqueous solutions?
Atoms whose outer electron shells contain eight electrons tend to be stable and do not easily form ionic bonds in aqueous solutions. This is because they have reached the stable configuration known as the octet rule. In most cases, atoms that form ionic bonds have outer electron shells that are not fully filled with eight electrons.
Why noble gasses are not active?
Noble gases are not active because of their outer shells. The outer shells of these gases are full of 8 valence electrons, which make them stable and inert.
How many electrons do the elements of the most stable group have in their outer shells?
Elements in the most stable group of the periodic table, also known as the noble gases, have full outer shells. This means they have 2 electrons in the case of helium, and 8 electrons for all other noble gases.
When a stable molecule is formed what is the configuration of its atoms' outer shells?
In a stable molecule, the atoms' outer shells are typically fully filled with electrons according to the octet rule. This means that the atoms have achieved a stable configuration by either sharing, gaining, or losing electrons to reach a full outer shell of valence electrons. This configuration makes the molecule less reactive and more stable.
Which bond help with filling electrons with outer shells?
Ionic bonds help fill the outer shells of atoms by transferring electrons from one atom to another. This results in the atoms achieving a stable electron configuration similar to a noble gas.
What is the most important factor in an elements place in the periodic table?
Its elemental weight
What is the chemical behavior of atoms whose outer electron shells contain 8 electrons?
These atoms are very stable and unreactive.
