Which statement describes all types of matter?
The correct answer for the question above is letter a. It takes up space and has mass. It is the best statement that describes all types of matter.
What statement best describes a liquid?
A liquid has a definite shape and volume. A liquid has a definite volume but not a definite shape. A liquid expands to fill the shape and volume of its container. A liquid cannot flow.
Which property of physical changes explains why?
That is, arrangement of atoms changes and bond between the atoms do no break during a physical change. Thus, we can conclude that the property bonds between atoms do not break; it is only the arrangement that changes explains why matter is conserved in a physical change.
Which term best describes all atoms in ionic bonds?
Answer : The correct option is A) Stable. Explanation : Ionic compound : Ionic compounds are the compounds which are made up of an ions that are cations and an anions. The ionic bonds are stable when cation and an anions both approaches to each other by electrostatic force, they form ionic bonding.
What best describes an ion?
An ion is a charged atom or molecule. When an atom is attracted to another atom because it has an unequal number of electrons and protons, the atom is called an ION. If the atom has more electrons than protons, it is a negative ion, or ANION. If it has more protons than electrons,it is a positive ion.
Is the only element in Group 1 that forms covalent bonds?
Hydrogen is the only non metal in group 1 therefore it is the only element in group 1 that form covalent bond.
Can a covalent bond be between metal and nonmetal?
It’s possible for a metal and a nonmetal to form bonds with high covalent character. Copper(II) chloride, CuCl2, is a good example. The percent ionic character for Cu-Cl bonds is 33%, and 67% covalent character. But for the bonds to be nonpolar the electronegativity of the metal and nonmetal must be the same.
Could a pair of metal atoms form a covalent bond?
Metals simply do not hold on to electrons with enough strength to form much in the way of covalent bonds. For a covalent bond to form, we need two atoms that both attract electrons with high electron affinity.
Is a metal lattice rigid?
attraction between a metal cation and shared pool of electrons. metal lattice is extremely rigid, B. bonds within a metal lattice are weak, C. Electrons in a metal lattice are free to move, or D.
Are the bonds within a metal lattice weak?
The metallic bond is somewhat weaker than the ionic and covalent bond. Ionic bonds are strong electrostatic attraction forces formed between positive and negative ions. This bond is non-directional, meaning that the pull of the electrons does not favor one atom over another.
