Darya [45]

Answer: False

Explanation: There are four carbon atoms , eight hydrogen atoms and two Bromine atoms.

As the carbon forms four covalent bonds, every carbon must have four bonds and thus the formula of the compound is BrCH_2-CH(Br)-CH_2-CH_3.

IUPAC name of the compound is 1,2 di-bromobutane. As the carbon chain is 4 atoms long the word used is but and all the bonds are single bonds, thus the suffix used is ane.

mafiozo [28]

Nitrogen has 7 protons, 7 neutrons, and 7 electrons.

Seven protons, seven neutrons, and seven electrons make up nitrogen-14.

Utilize the atomic number and mass number of an atom to determine the number of subatomic particles it contains: Atomic number Equals proton count. Electron count equals atomic number. Atomic number - mass number equals the number of neutrons.

Seven protons, seven neutrons, and seven electrons make up the atom of nitrogen. The nucleus is the collection of protons and neutrons that make up the center of an atom. The 7 electrons, which are much smaller than the nucleus, orbit it in what is known as orbits. Since nitrogen-14 is a neutral atom, the number of protons in its nucleus must match the number of electrons around it.
