Science 4-5,6

valence electron electron in the outermost energy level of an atom
ion atom with an electrical charge
ionic bond bond formed between atoms that have gained or lost electrons
What are valence electrons? Valence electrons are electrons in the outermost energy level of an atom.
Why are atoms neutral? Atoms are neutral because the number of electrons is equal to the number of protons.
Does a negative ion have more protons or more electrons? A negative ion has more electrons than protons.
How does an ionic bond from? An ionic bond forms when one atom gains one or more electrons from another atom and forms two ions, one positively charged and one negatively charged, and the two ions attract thus forming an atomic bond.
What is a crystal? A crystal is a solid that contains atoms arranged in a regular pattern.
covalent bond bond formed when atoms share electrons
How can atoms complete their outermost energy levels? Atoms can complete their outermost energy level by gaining, losing; or sharing electrons.
Is water an ionic compound or a covalent compound? Water is an covalent compound.
How are covalent compounds different than ionic compounds? Covalent compounds and ionic compounds are different because in an ionic compound atoms form ions and gain or lose electrons and in a covalent compound, atoms remain neutral and share electrons.
What do electron dot diagrams show? Electron dot diagrams show the position of valence electrons.
