What is the lithium main electron level?
The electron valence shell has 1 electron.
What is the Lewis dot structure for BrO3 -1?
Br is in the center with single bonds going out to each of the 3 surrounding oxygen. Br has 1 lone pair and each of the oxygens have three lone pairs.
The outer electron configuration of an alkali metal has?
1 electron in the s orbital
What has a mass of 0 amu and a charge of -1?
The electron has a charge of -1; but the electron has a mass.
What is the electron mass an atom?
an electron is about 1/1836 amu.
What is the electron domain geometry for pf3?
3 bondings + 1 electron pair = 4 (electron domains)
Is BrO3 -1 ionic or covalent?
BrO3
What is the electron geometry of ICl4-1?
Planar with an angle of 90 dergrees
Molecular shape of PH3?
PH3 has 3 bonding pairs and 1 non-bonding pair of electrons. Its electron pair geometry is Tetrahedral and its molecular geometry is Trigonal Pyramidal.
What is the molecular geometry of a molecule with 5 outer atoms and 1 lone pair on the central atom?
Anything with six electron groups, keep in mind an electron group is a bonded atom or an electron pair, is an octahedral. Anything in an octahedral and a lone pair is the square pyramidal geometry. So all angles between the atoms are a little less than 90 degrees and the angle of the electron pair is greater than 90.
What is the correct name for the BrO4 -1 ion?
Tribromine octoxide.
What is the electron-domain geometry of XeF4?
Remember, the geometry of a molecule has to do with how many electron pairs AND lone pairs there are around the CENTRAL atom. Basically, count up the lines and the pairs of dots. Notice that 'Xe' has 8 electrons in its valence shell, and 'F' has only 7. When we put 4 'F' atoms around 1 'Xe' atom, each Flourine atom is going to want to 'share' one of Xenon's electrons so that it can have 8 electrons. Also remember that when an atom shares electrons, it shares in pairs. Each shared bond has 2 electrons. Now count up the number of electron PAIRS around the CENTRAL atom. We have 4 bonds (one with each Fluorine atom), and 2 lone pairs of of electrons bringing our count up to 12 electrons around Xenon, or 6 pairs total. (This violates the 'Octet Rule', but it's ok in this situation) Here is a list of geometries according to the number of Electron Domains: 2 'ED's (electron domains) = Linear shape 3 'ED's = Trigonal Planar 4 'ED's = Tetrahedral 5 'ED's = Trigonal Bi-pyramid 6 'ED's = Octahedral The electron-domain geometry of XeF4 would be Octahedral. Hope this helped!
What is bromines chemical symbol?
Bromate is a polyatomic ion made of Bromine and oxygen: BrO3-
Why is the oxidation number of Br in BrO3 5?
BrO3 is an anion of minus one (-1) charge. BrO3^-1 Using oxygen as the standard at '-2' Then the oxygen moiety is 3 X -2 = -6 So doing a 'little' sum -6 + Br = -1 Add '6' to both sides Br = 5 (The oxidation number of Br). NB Using '-2' for oxygen is a good standard for most molecules/ions. However, oxygen's oxidation number does vary , but not in very many molecules/ions.
What is the oxidation number for Br in BrO3-?
If Br had an oxidation number of +7, the net charge on the ion would be +1, and not -1. Thus, the oxidation number for Br in BrO3- should be 5+.
Do you have to take algebra 1 before you take geometry?
YEAH! Algebra 1 comes before geometry.
What type of math is higher between algebra 1 or geometry?
it goes algebra 1, geometry, then algebra 2
