How many electrons does He and Ca have in its outer shell?
Helium (He) has 2 electrons in its outer shell. Calcium (Ca) has 2 electrons in its inner shell and 8 electrons in its outer shell.
Does the Ca plus 2 ion have more electrons than the Ca atom?
No, Ca2+ has 2 electrons LESS than Ca
How many elements have two valence electrons?
Examples: Ca, Mg, Ba, Sr, Ra, etc.
How many electrons must be lost given the following atoms Ca Mg Ba Be to attain Noble gas?
To attain the noble gas configuration, Ca would have to lose 2 electrons, Mg would have to lose 2 electrons, Ba would have to lose 2 electrons, and Be would have to lose 2 electrons.
How many electrons will a calcium atom Ca lose in order to get a noble gas configuration?
Calcium will lose two electrons to gain the noble gas configuration of Argon.
How many electrons does Ca?
Two
How many electrons does He and Ca have in its outer shell?
Helium (He) has 2 electrons in its outer shell. Calcium (Ca) has 2 electrons in its inner shell and 8 electrons in its outer shell.
How many electrons does Ca lose?
2
How many electrons are in the isotope Ca-42?
If 42 is the atomic number then there is 42 electrons in isotope.
How many electrons must be gained or lost for calcium to attain a noble gas electron configuration?
Ca needs to lose 2 electrons to become Ca+2
How many electrons are lost when ca plus 2 is formed?
Two.
How many electrons gained or lost for calcium?
Ca loses electrons. In general metals react in compound by losing some of their electrons, Ca is a metal.
Does the Ca plus 2 ion have more electrons than the Ca atom?
No, Ca2+ has 2 electrons LESS than Ca
How many electrons are in the n1 shell?
There can be 10 electrons in the n=2 shell. Two can fit in the 1s orbital, two can fit in the 2s orbital, and six can fit in the 2p orbital.
What is the Lewis dot structure for calcium?
Cl-Cr-Cl
How many valence electrons are found in an atom of Ca?
There are two valence electrons in Ca. To determine this write out the electronic configuration of Ca using the Principal quantum number method K L M N 2 8 8 2 as you can see the number of electrons in the outermost shell (which is the valency) is 2. Making Ca a metal and giving away its 2q outermost electrons to attain a stable electronic configuration.
Describe the sequence 25 26 24 27 23?
n1= 25 n2= n1+1 n3= n1-1 n4=n1+2 n5=n1-2
