Which sublevel contains valence electrons in an atom of magnesium?
In an atom of magnesium, the valence electrons are found in the 3s sublevel. Magnesium has an atomic number of 12, which means it has two electrons in the 1s sublevel, two in the 2s, and eight in the 2p, leaving two electrons in the 3s sublevel as its valence electrons.
How many valence electrons does magne sium have?
A magnesium atom has 2 electrons in its valence shell. A magnesium ion has 8 electrons in its valence shell.
What is a valence shell of mg?
The valence shell of magnesium (Mg) contains 2 electrons in the outermost energy level. This is because magnesium is an alkaline earth metal with 2 valence electrons. These electrons are located in the 3s orbital in the third energy level.
What sublevel in group 2 elements are valence electrons?
s
Which element have two valence electrons?
Calcium (Ca) has two valence electrons.
When transition elements react chemically they may lose electrons from which sublevel?
Transition elements can lose electrons from their d sublevel when they react chemically. This is because the d sublevel contains the valence electrons involved in bonding for transition elements.
