What element has 4 energy levels and 5 valence electrons and is a metalloid?

What element has 4 energy levels and 5 valence electrons and is a metalloid?

Arsenic
NITROGEN FAMILY: All have 5 VALENCE ELECTRONS (electrons in the outer energy level) Nitrogen and phosphorous are NONMETALS. Arsenic and Antimony are METALLOIDS.

Does Arsenic have 5 valence electrons and 4 energy levels?

So we can see that the electron configuration for arsenic has 5 electrons in the valence shell of the 4th energy level.

What elements contain 4 energy levels?

Since potassium, calcium, and bromine are in the 4th row or period, their outermost electrons are in the fourth energy level.

What is the only metal with 5 valence electrons?

Arsenic (As) (Figure below) and antimony (Sb) are the metalloids in this group, and bismuth (Bi) is a metal. All group 15 elements have five valence electrons, but they vary in their reactivity.

What element has 5 energy levels and 7 valence electrons?

Chlorine is a member of the group of atoms on the periodic table called the halogens. They are all one electron away from the noble gases which are highly stable compounds. Chlorine has 7 valence shell electrons, 2 in the 3s orbital and 5 in the 3p orbital. Since a…

What element is in the 4th period and Group 5A?

We are given with 5 valence electrons, therefore we must find the element in group 5A. Going back to the periodic table, we find Arsenic (As) in period 4 and Group 5A.

Which element has 6 valence electrons and 4 energy levels?

Atomic carbon has six electrons: two inner shell (core) electrons in the 1s orbital, and four valence (outer most shell) electrons in the 2s and 2p orbitals.

Does hafnium have 4 valence electrons?
