What else can I help you with?
Generally a complete valence shell holds how many electrons.?
Generally, a compete valence shell holds EIGHT electrons.
True or false if valence electrons are shared between atoms the bond is said to be covalent?
True. In a covalent bond, atoms share valence electrons to achieve a full outer shell and form a stable molecule.
Is it true or false every element has the same valence?
False. Elements have different numbers of valence electrons, which determines their reactivity and chemical properties. The valence electrons are the electrons in the outermost energy level of an atom.
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.
Atoms of some elements can share three pairs of electrons. True or false?
True. Nitrogen can share three pairs of electrons and has a lone pair of electrons for a total of eight in it's valence shell
Is The valence shell is the innermost shell of electrons in an atom?
false
Is The valence shell the innermost shell of electrons in an atom.?
false
Carbon has six electrons in its valence shell True or False?
The number of valence electrons equals an atoms main group number. Carbon is in group 4, therefore carbon has 4 valence electrons.
Is an atom most stable when it has eight electrons in its outermost energy level?
Most Atoms are more stable when they have eight valence electrons. The more electrons, the more stable. So No, most atoms are MORE stable when they have eight valence electrons.
The sharing of valence electrons between atoms indicates an ionic bond rue or false?
False. Sharing valence electrons to make a bond creates a covalent bond, not an ionic bond.
Do ions have a full valence shell?
No, atoms with filled valence shells do not tend to form chemical bonds because a filled valence shell means the atom is already stable. It doesn't "want" to share with or take electrons from other atoms to become stable. Although sometimes, these atoms can be found in compounds, it takes a great deal of energy and forcing.
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.
