How many valence electron does Ca lose or gain to attain noble-gas electron configuration?
Calcium loses two electrons to obtain a noble-gas electron configuration.
What makes atoms have a stable electron configuration?
In order for an atom to be chemically stable it must have 8 valence electrons.
How many valence electrons does calcium lose?
Calcium loses 2 valence electron to become ionized.
Why is a filled valence shell often called an octet?
A filled valence shell often has 8 electrons, which is called an octet. This configuration is considered stable because it mimics the electron configuration of noble gases, which have full valence shells.
What have two valence electrons and get to a stable electron configuration by losing two electrons?
An atom with two valence electrons in its outermost energy level can achieve a stable electron configuration by losing two electrons. This process is known as ionization. By doing so, the atom becomes a positively charged ion, known as a cation, with a full outer energy level.
How many electrons does silicon need to gain or lose to have a stable electron configuration?
Four: All of its valence electrons. If a silicon atom loses four electrons, it has the stable electron configuration of neon, while if the atom gains four electrons it has the stable electron configuration of argon. A silicon atom can also form a stable compound, as contrasted with a stable electron configuration for a single atom, by sharing four electrons with one or more other atoms.
How many valence electron does Ca lose or gain to attain noble-gas electron configuration?
Calcium loses two electrons to obtain a noble-gas electron configuration.
What makes atoms have a stable electron configuration?
In order for an atom to be chemically stable it must have 8 valence electrons.
What is tin as a stable electron configuration?
Tin has 4 valence electrons. Because of this, Tin needs to lose the 4 electrons to make it stable. Thus the answer is SN4+
How many valence electrons does calcium lose?
Calcium loses 2 valence electron to become ionized.
How many valence electrons does bromine wants?
Bromine wants to have 8 valence electrons to achieve a stable electron configuration, following the octet rule. Bromine has 7 valence electrons in its neutral state, so it typically gains one electron to reach the desired 8 valence electrons.
How many electrons do halogens have to lose or gain to achieve a stable noble gas electron configuration?
They have to gain 1 electron. Halogens have 7 electrons in their valence shell and noble gasses have 8.
How many valence electrons does oxygen gain?
Oxygen tends to gain two electrons to complete its "octet", making it O2- with the electron configuration 1s22s22p6
How many valence electrons are in a sulfur atom and a sulfide ion?
A sulfur atom has 6 valence electrons, while a sulfide ion has 8 valence electrons because it gains two electrons to achieve a stable electron configuration.
How many more electrons does Fluorine need to have a stable octet?
Fluorine needs one more electron to have a stable octet, as it has 7 valence electrons and stable octet configuration is achieved with 8 electrons.
All atoms become stable when they have how many valence electrons?
Atoms become stable when they have a full outer electron shell, which typically means having 8 valence electrons (except for hydrogen and helium, which are stable with 2 valence electrons). This stable configuration is known as the octet rule.
Which element gains 2 electrons?
Oxygen gains 2 electrons to achieve a full valence shell with 8 electrons. This gives oxygen a stable electron configuration similar to the noble gas configuration.
