Abond formed when atoms transfer electrons is a(n) bond. covalent metallic ionic negative

ionic

Explanation:

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

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:

Metallic bond is the type of chemical bond which occurs between the atoms of a metals.This type of bonding arises due to electrostatic interaction between the electron cloud of  de-localized electrons with positively charges metal ions. Example:

let that person have a turn to speak : )

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
