What atom has two more protons and two more electrons than bromine?
Bromine has 35 protons and 35 electrons (if it is neutral). Rubidium has 37 protons and 37 electrons (if it is neutral as well). The atomic number is equivalent to the number of protons in an atom. You can easily solve this problem by looking at your periodic table, finding Bromine (Br) and then moving 2 atoms along the chart. There you will find Rubidium.
Which is more reactive bromine or iodine?
It is because bromine is smaller in size than iodine and hence easily reacts. Another reason is that bromine is the more electronegative than iodine and hence it attracts the electrons very easily from other atoms to form bonds.
Why is chlorine more reactive than bromine?
Chlorine is more reactive than bromine because it has a smaller atomic radius and higher effective nuclear charge, leading to stronger attraction for electrons. This makes it easier for chlorine to gain electrons and achieve a stable electron configuration through the formation of ionic or covalent bonds. Additionally, the higher electronegativity of chlorine compared to bromine also contributes to its greater reactivity in chemical reactions.
Why is it easier to remove an electron from bromine then it is to remove an electron from fluorine?
The reason why fluorine has a higher ionization energy level than oxygen is because it is closer to the nucleus than is oxygen, therefore, it will take more energy to pull electrons from the nucleus.
What is the most reactive element out of sodium neon argon and krypton?
Sodium. Neon, Argon, and Krypton are all inert gases. They don't react with pretty much anything. However, if you put a piece of sodium metal in water, it practically explodes, that's how reactive it is. Mainly because all it has in it's outermost electron shell is one electron, and so it wants to lose that one in order to be stable.
What atom has two more protons and two more electrons than bromine?
Bromine has 35 protons and 35 electrons (if it is neutral). Rubidium has 37 protons and 37 electrons (if it is neutral as well). The atomic number is equivalent to the number of protons in an atom. You can easily solve this problem by looking at your periodic table, finding Bromine (Br) and then moving 2 atoms along the chart. There you will find Rubidium.
Why does bromine have 7 valence electrons?
The element bromine has 35 protons in its nucleus, and therefore in its electrically neutral state it also has 35 electrons. Two electrons fit in the innermost shell, eight fit in the next shell, eighteen fit in the next shell, which takes the total up to 28. If we subtract 28 from 35 we get seven, voila.
Why does valence electron give up outermost energy easily?
The force of attraction between the atom's nucleus and its valence electrons are the least. Hence valence electrons are lost easily.
What kinds of object give up electrons easily?
Carpets and balloons both give up electrons easily.
Which is more reactive bromine or iodine?
It is because bromine is smaller in size than iodine and hence easily reacts. Another reason is that bromine is the more electronegative than iodine and hence it attracts the electrons very easily from other atoms to form bonds.
What particle can be removed from an atom easily?
Electrons can be removed easily from an atom because they are the outermost particles and have the least amount of attraction to the nucleus compared to protons and neutrons.
Does NH3 have lone pair electrons?
The lone pair of electrons in the ammonia molecule is located in the outermost electron shell of the ammonia molecule. This will enable it to easily form a bond with any compound that it is mixed with.
Which element would you expect to gain one electron in a chemical reaction?
Metals are the elements that usually lose electrons in their chemical reactions. This is because they have few electrons in their outermost shells which are easily lost.
Which elements can lose electrons from the two outermost shells?
Elements in Groups 1 and 2 (alkali metals and alkaline earth metals) can easily lose electrons from their outermost shells. Group 13 elements like Boron, as well as Group 17 elements like Halogens, can also lose or gain electrons from their two outermost shells, though the valency may vary.
Why is it significant that valence electrons are located in the outermost energy level of an atom?
Valence electrons are involved in chemical bonding and determining an atom's reactivity. As they are located in the outermost energy level, they are more easily shared or transferred with other atoms to form bonds, making them crucial in determining the atom's chemical properties and behavior.
Halides 7 valence electrons?
Halides with 7 valence electrons typically have a -1 charge, such as chlorine (Cl-) and bromine (Br-). These elements can easily gain one electron to form a stable octet configuration.
Which electrons have the most energy in an atom?
All electrons in an atom have: * a negative one charge * 1/2 spin * 0.511 MeV of mass
