A chemical consisting of an aluminum ion and a bromide ion in their stable states would be AlBr2+, but it is not an ionic compound because it has a charge. Bromine atoms tend to gain just one electron to get to a full octet, as Bromine is in Group VII. The bromine has an octet because it has two electrons from the H-Br bond and six more electrons, two in each lone pair on Br. It was the first element to be extracted from seawater, but this is now only economically viable at the Dead Sea, Israel, which is particularly rich in bromide (up to 0.5%).

This reactivity is due to high electronegativity and high effective nuclear charge. Halogens can gain an electron by reacting with atoms of other elements. Asked By: Gene Steinbuck | Last Updated: 19th June, 2020, Moving from neutral to +3 charge means it just lost 3 electrons. Expert Answer . its in notice that Sn is in the part of the table (columns 13-18) where the p-orbitals are filling (since it's in the 5th column, it has 5 valence electrons in the p orbitals). Hydrogen and carbon have similar electronegativity values, so the C—H bond is not normally considered a polar covalent bond. It shares one electron with the hydrogen atom. Fluorine is one of the most reactive elements. Nicky B. 2.

Hydrogen has only one valence electron because it is in the first group. to achieve stable octet electron arrangement (full valence shell), the valence shell must have 8 electrons. Thus it tends to lose two electrons. Helium atom has 2 electrons in its valence shell. There are three violations to the octet rule. lollipop. The s and p orbitals are generally the orbitals on the furthest outside of an element. Bromine belongs to group 17 (or group VII, Roman character). Tags: Question 12 . If p-oritals are filling, then the s-orbitals are already full (add 2 more valence electrons). So, what you need to do is round the atomic weight to the nearest whole number to get a mass number for your calculations. Secondly, how many bonds can bromine have? A. Answer Save. The number of protons is equal to the number of electrons in an electrically neutral atom, so there are 35 electrons in a bromine atom. 15. How will K most likely become stable?
