Abond formed between a silicon atom and an oxygen atom is likely to be

Polar covalent

Explanation:

a) A covalent bond is formed when an element shares its valence electron with another element. This bond is formed between two non metals.

Types of covalent bonds:

A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms. Example:

Non-polar covalent bond is defined as the bond which is formed when there is no difference of electronegativities between the atoms.Example:

b) An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and the element which accepts the electrons is known as electronegative element. This bond is formed between a metal and an non-metal. Example:

sure what is it? ^w^

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
