Quick Answer: How Many Electrons Does Br Want?

What is the charge of Br?

A bromide is a chemical compound containing a bromide ion or ligand.

This is a bromine atom with an ionic charge of −1 (Br−); for example, in caesium bromide, caesium cations (Cs+) are electrically attracted to bromide anions (Br−) to form the electrically neutral ionic compound CsBr..

Does oxygen gain or lose electrons?

Elements in Groups 15,16 and 17, find it easier to gain electrons than lose them. For example, oxygen atoms gain two electrons to form O2- ions. These have the same electron configuration as the noble gas neon. Elements in Group 14 could lose four, or gain four electrons to achieve a noble gas structure.

How many neutrons does BR 1 have?

45 neutronsSo Bromine Br−1 has 35 protons, 36 electrons and 45 neutrons.

Does BR have 8 valence electrons?

The atomic number for bromine is 35, which means it has 35 protons in its atomic nuclei. A neutral bromine atom would also have 35 electrons. … Below is the Lewis dot structure for a Br− ion, which has eight valence electrons. The extra valence electron gives it a negative charge.

How many energy levels does BR have?

Number of Energy Levels:4First Energy Level:2Second Energy Level:8Third Energy Level:18Fourth Energy Level:7

Is BR a metal?

Bromine is a non-metal in group 17, period 4 of the periodic table. Pure bromine exists as a brown liquid at standard temperature and pressure.

Why does BR have 7 valence electrons?

Valence electrons found in the s and p orbitals of the highest energy. Bromine has an electron configuration of 1s22s22p63s23p64s23d104p5 the valence electrons are in the 4s and 4p orbitals giving Bromine 7 valence electrons.

What group is Br?

Bromine (Br), chemical element, a deep red noxious liquid, and a member of the halogen elements, or Group 17 (Group VIIa) of the periodic table.

Which element is a noble gas ne or Br or O?

The six naturally occurring noble gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn).

How many electrons are in each shell?

Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.

Can bromine kill you?

Bromine vapors are very toxic with inhalation. Humans can absorb organic bromines through the skin, with food and during breathing. Organic bromines are widely used as sprays to kill insects and other unwanted pests. … Some forms of organic bromines, such as ethylene bromine, can even cause cancer.

What happens when bromine gains an electron?

The neutral atom of bromine has 35 electrons because the number of electrons equals the number of protons. … When bromine gains an electron, the resulting ion is called an anion and is negatively charged.

How many valence E does BR have?

7 valence electronsBromine has 7 valence electrons and the valency of bromine is 1.
