Answer:
It has 3 sigma bonds
Explanation:
A sigma bond is a covalent interaction between two atoms, these bonds are the strongest type of covalent bonds and they are formed by the overlap of atomic orbitals.
The nitrogen is bond to the bromine atoms through sigma bonds, which means that exist 3 sigma bonds in the molecule.
this molecule has a trigonal pyramid geometry due to the free pair of nitrogen electrons.
Answer:
The majority of the molecules move from higher to lower concentration, although there will be some that move from low to high. The overall (or net) movement is thus from high to low concentration.
hope this helps!<3
The overall charge on this atom is zero if the lithium atom has three, protons, three neutrons, and three electrons.
<h3>What is an atom?</h3>
The smallest tiny particles of matter which can't be divided further is called atoms.
The lithium atom is always electrically neutral, ie, it has no charge. A proton has a unit positive charge while an electron has a unit negative charge, an atom has an equal number of protons and neutrons and thus it is electrically neutral.
Hence, the overall charge on this atom is zero if the lithium atom has three, protons, three neutrons, and three electrons.

See Figure 4 below.
1. Draw a 7-carbon chain and number the carbon atoms (<em>Figure 1</em>).
2. Insert a triple bond between atoms 5 and 6 (<em>Figure 2</em>).
3. Attach a phenyl group to atom 3 (<em>Figure 3</em>).
4. Attach a Br to atom 1 (Figure 4).
And you have your structure.
<em>Note</em>: The C≡C triple bond takes <em>priority</em> in the naming, so we must number the chain from the other end. The correct name is
<em>7-bromo-5-phenylhept-2-yne </em>(all one word).
