calcium has the complete electronic configuration: 2, 8, 8 2 and hence has 2 valence electrons.
What else can I help you with?
When a calcium atom loses its valence electrons the ion formed has an electron configuration that is the same as an atom of?
Argon. Calcium has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2, and when it loses its valence electrons (the outermost 4s2 electrons) it has a configuration identical to argon. If you don't know about sublevels, then disregard that. Calcium has a configuration of 2-8-8-2, and when it loses its 2 valence electrons, it has a configuration identical to argon in the ground state. Hope that cleared it up
What is the electron dot configuration for calcium?
Calcium has two valence electrons, both of which are unpaired. •Ca•
How many valence electrons are transferred from the calcium atom to iodine in the formatoin of the compound calcium iodide?
during the formation of calcium iodide,calcium donates two of its +ve ions each to a fluorine atom(2 in number) thereby making its octet and also fulfills the octet formation of each of fluorine atom..
What is the valence electron configuration for the phosphorus atom?
The valence electrons are the outermost (highest energy) s and p sublevels. There are 5 valence electrons in a phosphorus atom, and it is in period 3, so its valence electron configuration is 3s23p3.
What is the valence electron configuration for the magnesium atom?
Magnesium (Mg) has atomic number 12, so the electron configuration is1s2 2s2 2p6 3s2. The VALENCE electron configuration would simply be 3s2.
How can one determine the number of valence electrons in an atom using its electron configuration?
To determine the number of valence electrons in an atom using its electron configuration, look at the highest energy level (n) in the electron configuration. The number of electrons in this energy level is the number of valence electrons.
How many valence electrons does an atom of potassium have?
4
If calcium has two valence electrons in sulfur have six how many calcium Adams are needed to form an ionic bond with sulfur?
One calcium atom will form an ionic bond with one sulfur atom, since calcium will donate its two valence electrons to sulfur in order to achieve a stable electron configuration.
How can one determine the number of valence electrons in an atom based on its electron configuration?
To determine the number of valence electrons in an atom based on its electron configuration, look at the outermost energy level of the atom. The number of electrons in this energy level is the number of valence electrons.
How can one differentiate valence electrons from electron configuration?
Valence electrons are the outermost electrons in an atom that are involved in chemical bonding, while electron configuration refers to the arrangement of electrons in an atom's energy levels or shells.
How many electrons are there in the neutral atom which has the ground state outer electron configuration of 4s2?
Calcium has the electron configuration [Ar]4s2; the neutral atom of calcium has 20 electrons.
What is the number of electrons a calcium atom must gain or lose to have 8 valence electrons?
A calcium atom must lose 2 electrons to have 8 valence electrons, achieving a full outer shell and stability. Calcium is in group 2 of the periodic table, so it has 2 valence electrons originally. By losing 2 electrons, it will have a stable electron configuration similar to a noble gas.
