A charged atom is called an ion. Atoms are neutral because they have the same numbers of positive and negative charges. By adding or taking away negative charges, atoms can become positive or negative.
Protons and neutrons exist in the nucleus of an atom. Protons have a positive charge, whereas a neutron has no charge. Electrons are negatively charged particles that zoom around the nucleus.
Some elements are electropositive, while others are more electronegative. Atoms like to have a full outer electron shell, so they either try to gain or lose electrons to fill their outer shells. Electropositive elements such as lithium, whose atoms have few electrons in their outer level, will donate them to other atoms. They then become positively charged because they have more protons than electrons. Elements such as oxygen are electronegative and want to take electrons from other atoms, thus gaining a negative charge.Learn More
The atoms involved in ionic bonding are held together by an electrostatic force of attraction between a positive and a negative ion. Ionic bonds are only formed between metals and non-metals.Full Answer >
Alkanes have no double or triple bonds, alkenes have one or more double bonds and alkynes have one or more triple bonds. Alkanes, alkenes and alkynes are all types of hydrocarbons.Full Answer >
An atom of boron has three valence electrons. The valence electrons of boron occupy the second orbit around the nucleus of the boron atom. Thus, the boron atom has an electronic configuration of [He] 2s2 2p1.Full Answer >
The element phosphorus has five valence electrons. Valence electrons refer to the amount of electrons in the outer shell of an atom. If an orbital is not full of atoms, it is likely to try to fill or deplete it in order to become more stable.Full Answer >
