What type of bond is NaBr?
ionically
Is sodium bromide a covalent or ionic? Sodium bromide is an ionically bonded compound. The electronegativity of bromine is high enough and that the electromagnetic force between the Br and the Na atoms is great enough that an electron is transferred from the Na atom to the Br atom.
What is the coordination number of sodium bromide?
The coordination number is the number of ions that immediately surround an ion of the opposite charge within a crystal lattice. If you examine the figure below, you will see that there are six chloride ions immediately surrounding a single sodium ion. The coordination number of sodium is 6.
What are two properties of sodium bromide?
Sodium bromide is an inorganic compound with the formula NaBr….Sodium bromide.

What type of bond is between Na and Br?
NaBr is an ionic compound. Bromine has enough electronegativity that the electromagnetic force between the Br and the Na atoms is great enough that an electron transfers from the Na atom to the Br atom. So Br becomes negatively charged and Na becomes positively charged.
What type of bond is found in sulfur dioxide?
Sulfur dioxide is a Covalent compound because, in the case of sulfur dioxide, two atoms possessing similar electronegativity try to bond together. In doing so, the slight difference of electronegativity between the two atoms results in sharing of electron bonds forming covalent bonds.
Is BR a bromine?
Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour.
What is the formula for sodium bromate?
NaBrO3
Sodium bromate/Formula
CHEBI:75229 – sodium bromate. An inorganic sodium salt having bromate as the counterion. Sodium bromate, the inorganic compound with the chemical formula of NaBrO3, is the sodium salt of bromic acid.
Is sodium bromide negative or positive?
Sodium Bromide Structure – NaBr Sodium is a positively charged radical, which is very unstable because it is a highly reactive metal.
What type of bonds are in co2?
Note that carbon dioxide has two covalent bonds between each oxygen atom and the carbon atom, which is shown here as two lines and referred to as a double bond. When molecules are symmetrical, however, the atoms pull equally on the electrons and the charge distribution is uniform. Symmetrical molecules are nonpolar.
What is the formula of sulfur dioxide?
SO₂
Sulfur dioxide/Formula
How does sulfur and oxygen bond?
Double bonds between sulfur and oxygen or carbon atoms can be found in compounds such as SO2 and CS2 (see figure below). double bond is 745 kJ/mol. Elemental oxygen consists of O2 molecules in which each atom completes its octet of valence electrons by sharing two pairs of electrons with a single neighboring atom.
Which is the best legal definition of rational?
Legal Definition of rational. 2 : relating to, based on, or guided by reason, principle, fairness, logic, a legitimate state interest, or a consideration of fact age distinctions are not subject to strict scrutiny, but they must have a rational relationship to a legitimate state…
Is the number 1.5 a rational or irrational number?
However, if you can’t turn -1.5 into a whole fraction, then -1.5 is an irrational number, not a rational number. If you find it helpful to look at a list of examples of negative irrational numbers, in order to more easily be able to classify negative numbers, the following numbers are all negative irrational numbers, -2, -13 and -8.
What is the medical definition of rational behavior?
Medical Definition of rational. 1a : having reason or understanding. b : relating to, based on, or agreeable to reason a rational explanation rational behavior. 2 : using medical treatments based on reason or general principles —used especially of an ancient school of physicians — compare empirical sense 1a.
Can a number be written down as a rational number?
Whereas their opposite, irrational numbers can’t be written down as a simple whole fraction. You may be surprised to read that both decimal figures and negative figures can be classed as irrational numbers as well as rational numbers.
