What Elements like calcium located toward the top of a group have a high attraction for their valence electrons because the have a?
Elements like calcium located toward the top of a group have a high attraction for their valence electrons because they have a relatively low atomic size and therefore a stronger effective nuclear charge. This results in a greater tendency for these elements to attract and hold onto their valence electrons.
What else can I help you with?
Which has a greater attraction for electrons Ca or O?
Oxygen (O) has a greater attraction for electrons compared to calcium (Ca) due to its higher electronegativity. Oxygen, being a non-metal, has a higher tendency to attract and share electrons in chemical reactions, while calcium, being a metal, typically loses electrons to form cations.
How many valence electron does calcium have?
Calcium has 2 valence electrons, like all Group 2 elements.
Is calcium a lender giver or sharer of electrons?
Calcium is a lender of electrons because it tends to lose two electrons to achieve a stable electron configuration. It forms ionic bonds by giving away these electrons to elements that need to gain electrons to achieve stability.
Which elements have 2 electrons in the 4s sublevel?
The elements that have 2 electrons in the 4s sublevel are calcium (Ca) and scandium (Sc).
How many valence electrons does and atom of Calcium have?
Calcium has 20 protons and 20 electrons. When we fill in the first 20 orbitals, we get the configuration of 1s2 2s2 2p6 3s2 3p6 4s2. Since 4 is the outermost shell in this configuration, calcium has 2 valence electrons.
Elements, like calcium, located toward the top of a group have a high attraction for their valence electrons because they have a _?
small atomic radius.

Why is it harder to remove an electron from Magnesium than it is to remove an electron from Calcium?
Zinc has more electrons in its outer energy level than Calcium. Because of this, itsnucleus is more attracted to this energy level and pulls it more the nucleus in Calcium. Because of this greater attraction it is harder to remove the electron from Zinc.
How many valence electrons does and atom of Calcium have?
Calcium has 20 protons and 20 electrons. When we fill in the first 20 orbitals, we get the configuration of 1s2 2s2 2p6 3s2 3p6 4s2. Since 4 is the outermost shell in this configuration, calcium has 2 valence electrons.
What are the elements that formed the calcium?
Calcium is an element, which means that it is made up protons/electrons and neutrons. Each calcium atom contains a total of 20 protons/electrons, and 20 neutrons.
Which element is more likely to combine with other elements calcium or xenon how do you know?
Calcium is more likely to combine with other elements because it is a metal with a tendency to lose electrons to form positive ions, while xenon is a noble gas with a stable electron configuration and tends to not form chemical bonds with other elements.
Which elements have the same number of valence electrons as beryllium?
For example calcium and magnesium.
How many s electrons are there in calcium?
The neutral atom of calcium has 20 electrons.
What elements have 2 valance electrons?
The entire Group 2A has 2 valence electrons; this includes sodium and calcium.
