Why is bromine not a metal?
Bromine, being in the second column from the rigth of the periodic table has a high electronegativity so when it forms compounds it tends to gain electrons, in other words, it is a nonmetal. While metals, which have low electronegativities tend to lose electrons
How many electrons must bromine br gain or lose?
Boron can lose 3 electrons from its valence shell that is 2 in 2s & 1 in 2p sub-shell, wheras it cannot gain electron b'coz of its electropositive nature & it has less electron affinity.
When more valence electrons of metal are shared it's melting point tends to be?
it melting point tends to be higher
What it tends to happen if sulfur combines with magnesium?
it will lose six electrons.
Does nitrogen give or take electrons?
Nitrogen is a nonmetal with 5 valance electrons, which tends to receive three electrons to complete it outer electron shell.
Does bromine tend to react by gaining electrons?
When a bromine atom reacts with a metal, it tends to gain an electron from the metal.
Why does nitrogen not normally react with oxygen?
Oxidation potential is too low. N tends to gain electrons.

Will an atom containing two electrons in its outer orbit loose or gain electrons to form an ionic bond?
An atom with incomplete octet tends to attain the noble gas configuration by the gain or loss of electrons. If an atom contains 2 electrons in its outer orbit, it would be more energy efficient for it to lose the two electrons and complete the octet, as opposed to gaining 6 electrons for the same.
Why is chlorine more reactive than bromine?
In most cases, chlorine is more reactive than bromine. This occurs because chlorine has a higher electronegativity than bromine. Thus, chlorine tends to take electrons from other substances more readily than bromine, and thus is more reactive.
What is the charge on an oxygen atom?
Corrected: All atoms have a neutral charge until they lose or gain electrons. Once they lose/gain electrons then they are considered ions with respectively positive (on loosing) or negative charge (on gaining electrons, as oxygen tends to do).NO: 2-. It's the same as minus 2, but is written as 2- for conventions.
Does fluorine gain or loose electrons?
Fluorine tends to gain electrons
Why is formula of calcium bromide CaBr2?
as you know, in writting a formula the valencies interchanges, if you remember the valency of calcium is 2, because it is the 20th element, and the valency of bromine is 3,so that atom of bromine we know is 3,but remember that bromine is a transition metal in five blocks of metals, this means that it can adopt the characteristics of its peer reactant,so in general anyway bromine react with calcium its valency tends to be 1(in other ways it is not must to be written), which after it reacts witso that is why you can see as it is! Bromine with 2 valencies and calcium with only one. i hope i tried to answer, thanks.
What is metal activators?
An active metal is a type of a metal that tends to react with toughness, and speed, to other elements because of the arrangement of electrons in its structure. Each active metal has a single electron in its outer shell.
What type of element tends to lose electrons?
Metals
What tends to take on electrons in order to become stable?
Nonmetals
