WHAT How many dots are shown in the electron dot diagram for calcium in group II and period 4 with 20 protons and 20 electrons?
In the electron dot diagram for calcium (Ca), which is in group II and period 4, there are two dots shown. These dots represent the two valence electrons in the outermost shell, as calcium has an atomic number of 20, meaning it has 20 electrons in total. The remaining electrons are in inner shells and are not represented in the dot diagram.
What else can I help you with?
What is the protons and electrons of element calcium?
Calcium has an atomic number of 20. Thus calcium's number of protons is 20. To balance out these protons' positive charges, calcium also is found with 20 negatively charged electrons.
How many protons and electrons does each calcium have?
Calcium (element number 20) has 20 protons and 20 electrons.
How many protons and electrons does a calcium atom have?
Calcium has 20 protons, 20 electrons and 20 neutrons in its most commonly found isotope.
What is a labeled diagram to show the structure of an oxygen atom?
A labeled diagram of an oxygen atom typically includes a central nucleus containing eight protons and eight neutrons, surrounded by two energy levels of electrons. The first energy level holds two electrons, while the second holds six. The diagram often shows the protons and neutrons within the nucleus, with lines or circles representing the electron shells and dots or small circles for the electrons. Labels indicate the protons, neutrons, and electrons, as well as the nucleus and electron shells.
How many protons electrons and neutrons dose calcium have?
Calcium has 20 protons and electrons and a variable number of neutrons, depending on the isotope.
How many dots are shown in the electron dot diagram for calcium in group 2 and period 4 with 20 protons and 20 electrons?
Two dots are shown in the electron dot diagram for calcium in group 2 and period 4 with 20 protons and 20 electrons.
How many proton neutrons and electron does calcium have?
Calcium has 20 protons, 20 electrons and 20 neutrons in its most commonly found isotope.
What is the electron number of calcium-40?
The element Calcium (Ca) has 20 electrons according to its atomic number which is 20.
How many valence electron does Ca have?
Calcium's atomic number is 20. It therefore has 20 protons and 20 electrons. Since calcium is a group 2 element, 2 of those electrons are valence electrons.
How many electron ca2 plus?
Calcium has atomic number 20. A neutron calcium atom therefore has 20 protons and 20 electrons. Ca2+ has a charge of positive 2, so it must have 2 more protons than electrons. Ca2+ has 18 electrons.
What is the protons and electrons of element calcium?
Calcium has an atomic number of 20. Thus calcium's number of protons is 20. To balance out these protons' positive charges, calcium also is found with 20 negatively charged electrons.
How many protons electrons and calcium does carbon have?
carbon has : 36000 protons 124000 electrons 348850 calcium
How many protons and electrons does each calcium have?
Calcium (element number 20) has 20 protons and 20 electrons.
How do you make a calcium atom stable?
A calcium atom becomes stable by achieving a full outer electron shell, which contains 8 electrons. Calcium has 20 protons, so it typically forms ions by losing 2 electrons to achieve an electron configuration like that of a noble gas.
A positive two ion of calcium ca plus 2 would have how many protons electrons and neutrons?
A calcium ion with a charge of +2 has lost 2 electrons, resulting in an electron count of 18. Since calcium has an atomic number of 20, the number of protons remains at 20. To find the number of neutrons, subtract the number of protons (20) from the mass number (which can be found on the periodic table), which for calcium is 40, to get 20 neutrons.
How many protons and electrons does a calcium atom have?
Calcium has 20 protons, 20 electrons and 20 neutrons in its most commonly found isotope.
How many protons neutron and electrons calcium?
Calcium has 20 protons and electrons and a number of neutrons different for each isotope..
