The element that has 2 valence electrons and an Atomic Mass greater than argon (which has an atomic mass of about 39.95 u) is calcium (Ca). Calcium is located in Group 2 of the Periodic Table and has an atomic mass of approximately 40.08 u. It is an alkaline earth metal and is known for its role in biological systems and materials like bone.
What else can I help you with?
What element has more valence electrons that oxygen fewer valence electrons that neon more protons than sodium but fewer protons than argon?
there is no such element
What is odd element in the noble gases?
Helium is odd as it has 2 valence electrons while others have 8 valence electrons.
What element has more valence electrons than oxygenfewer valence electorns than neon more protons than sodium but fewer protons than argon?
Neon has 0 valence electrons so it is not possible to have an element with fewer valence electrons. There can, therefore, be no such element.
How many electrons are in argon- 38?
Argon-38 is a specific isotope of argon, and it has 18 electrons since the number of electrons in an element is determined by its atomic number.
How many valence does argon has?
Argon is a noble gas. It has a full valence shell and thus, 8 electrons.
When magnesium loses its valence electrons it has atomic structure of what element?
Argon
When magnesium loses its valence electrons it has the atomic structure of what element?
When magnesium loses its valence electrons, it forms a cation with the atomic structure of neon. This is because it will lose its two valence electrons to achieve a full octet like the nearest noble gas, which is neon.
Does argon have ten electrons?
No. The atomic number of argon is 18. So it has 18 protons and 18 electrons (out of these, 8 electrons are valence electrons and belong to the outermost shell).
What element have the same valence electrons as neon?
Argon(Ar) and Helium(He)
What element has more valence electrons than oxygenfewer valence electrons than neon more protons than sodium but fewer protons than argon?
Neon has 0 valence electrons so it is not possible to have an element with fewer valence electrons. There can, therefore, be no such element.
How many valence electrons are there argon?
8 valence electrons- 1s22s2p63s2p6
What element has more valence electrons that oxygen fewer valence electrons that neon more protons than sodium but fewer protons than argon?
there is no such element
How many valence electrons do argon has?
Argon is a noble gas. All noble gasses have 8 valence electrons. Thus argon has 8 valence electrons as well.
How many electrons are in argon the element?
All noble gasses have 8 valence electrons which means outer electrons. As for electrons overall, argon would have 18.
What is odd element in the noble gases?
Helium is odd as it has 2 valence electrons while others have 8 valence electrons.
What element has more valence electrons than oxygenfewer valence electorns than neon more protons than sodium but fewer protons than argon?
Neon has 0 valence electrons so it is not possible to have an element with fewer valence electrons. There can, therefore, be no such element.
How many electrons are in argon- 38?
Argon-38 is a specific isotope of argon, and it has 18 electrons since the number of electrons in an element is determined by its atomic number.
