Option A: 3

The atomic number of gallium atom is 31. It belongs to 13th group and 4th period of the periodic table.

The electronic configuration is as follows:

[Ar]3d^{10}4s^{2}4p^{1}

Here, Ar is the nearest noble gas.

The outermost electronic shells are 4s^{2}4p^{1}.

From the electronic configuration, valence electrons of  gallium are 3.

Select all that identify a covalent bond.
saw5 [17]

Heres the best help i can give you There is a couple different ways to determine if a bond is ionic or covalent. By definition, an ionic bond is between a metal and a nonmetal, and a covalent bond is between 2 nonmetals. So you usually just look at the periodic table and determine whether your compound is made of a metal/nonmetal or is just 2 nonmetals

Which term is de ned as the region in an atom where an electron is most likely to be located?
charle [14.2K]
Orbital
All atoms have the same number of electrons as protons. Negative electrons are attracted to the positive nucleus. This force of attraction keeps electrons constantly moving around the nucleus. The region where an electron is most likely to be found is called an orbital.
