What arethree alkaline-earth metals besides calcium?
Beryllium, magnesium and barium are three more alkaline earth metals.
How does the size of a beryllium atom compare with the size of an oxygen atom?
Oxygen is fairly smaller than Beryllium. The two have the same amount of orbital shells, but Oxygen has more protons, which pulls its electrons closer together, thus decreasing the overall size!
Which element is more reactive lithium of beryllium?
lithium
Why is calcium the most chemically active alkaline earth metal?
Calcium is the most chemically active alkaline earth metal because it has a relatively low ionization energy compared to its group counterparts, which allows it to easily lose its two valence electrons. This property makes calcium more reactive, particularly with water and acids, leading to the formation of hydroxides and salts. Additionally, its larger atomic size compared to beryllium and magnesium results in a weaker attraction between the nucleus and the valence electrons, further enhancing its reactivity.
What is the most reactive alkaline earth metal?
Radium (Ra), atomic number 88, is the most reactive alkaline earth metal. It has the most energy levels of all the alkaline earth metals therefore it's electrons are more easily taken away.
How many electrons does an ion of beryllium have if it has a -2 charge?
Beryllium is element 4, so the "neutral" atom would have 4 protons and 4 electrons. In order to have a "-2" charge, it would need 6 electrons.
Which two atoms will have their outer energy level filled with 2 electrons?
Helium (He) and Neon (Ne) will both have their outer energy level filled with 2 electrons.
Which atoms will have their outer energy level filled with 2 electrons?
There are more than two such atoms. Perhaps there was a list of atoms you had to chose from. Anyway, two such atoms are beryllium and magnesium.
Would beryllium or sodium have properties like to magnesium?
Sodium would have properties more similar to magnesium than beryllium. This is because sodium and magnesium are both in the same group/family (group 2) of the periodic table, known as the alkaline earth metals, whereas beryllium is in group 2. Sodium and magnesium share similar chemical behavior, such as forming similar types of compounds and reactions.
Would beryllium have properties more similar to magnesium?
Yes, beryllium would have properties more similar to magnesium because they are both alkaline earth metals with similar electron configurations and chemical properties. They both have a low density, high melting point, and are relatively reactive.
How many more valence electrons does magnesium need to have a full outer valence shell?
it needs six more electrons to have a full outer valence shell.
How many electrons does Magnesium need to complete the last shell?
A magnesium atom would need 6 electrons to complete its highest occupied electron shell. In practice, a magnesium atom almost never does this, because the energy required would be too great. Instead, the magnesium atom transfers 2 electrons to one or more atom that are more electronegative than magnesium and thereby forms a magnesium ion with an electrical charge of +2. In this ion, the highest occupied shell of a magnesium atom is completely empty of electrons.
What is the total number of electrons in a Mg2 positive ion?
The Magnesium atom will lose 2 of its electrons to become a Magnesium ion with 10 electrons. (Mg2+) How many electrons does a magnesium ion have? How many electrons does a fluoride ion have? How many electrons does a fluoride ion have?
Why is magnesium iodide more covalent than magnesium chloride?
Magnesium iodide is more covalent than magnesium chloride because iodine is a larger atom with more electron-electron repulsion between its electrons, making it easier for iodine to share electrons with magnesium in a covalent bond. This results in a more even sharing of electrons between magnesium and iodine, leading to a more covalent character in magnesium iodide compared to magnesium chloride.
What does hydrochloric acid and magnesium produce?
When hydrochloric acid reacts with magnesium, it produces magnesium chloride and hydrogen gas as the products. This is a single replacement reaction where the more reactive magnesium displaces hydrogen in the acid to form the products.
How many electron shells does the beryllium atom have?
Two energy shells. Made up as 1s2, 2s2 Shells 1 & 2 each have only 's' orbital and each orbital has only two electrons in it. The outer shell '2' is more energetic. The electrons are paired and spin in opposite directions to each other.
A magnesium ion differs from a magnesium atom because 1. two fewer neutrons. 2. one fewer electron. 3. one more electron. 4. two fewer electrons.?
A magnesium ion differs from a magnesium atom because it has two fewer electrons. When a magnesium atom loses two electrons, it forms a magnesium ion with a 2+ charge.
