There are 21 valence electrons in neutral BrF2, so there will be one unpaired. Draw each F having a shared pair, giving each F 8 electrons. The central Br atom will have 9 electrons.
If the charge is BrF2 there will only be 8 electrons around Br, if the charge is BrF2- then there will 10. BrF2+ is well known.
To draw a Lewis structure for Be2+, start by writing the symbol for beryllium. Since Be2+ has a 2+ charge, it has lost two electrons. Place the two electrons as individual dots around the beryllium symbol, as there is no other atom bonded to it. The Lewis structure for Be2+ is simply Be with two dots around it.

Mg2+
The ion PBr4⁺ has a central phosphorus atom surrounded by four bromine atoms. Since phosphorus can expand its octet, there are multiple resonance forms due to the possibility of different arrangements of double bonds and single bonds between phosphorus and the bromine atoms. Specifically, there are four equivalent Lewis structures that can be drawn for PBr4⁺, each showing a different bromine atom with a double bond to phosphorus while the others remain single-bonded. Thus, four resonance structures are necessary to accurately represent the bonding in PBr4⁺.
They are called chromosomes.Proteins are histone proteins.

Two equivalent Lewis structures are necessary to describe the bonding in NH4+ because nitrogen in the ammonium ion has a full octet and can form a single coordinate covalent bond with each of the four hydrogen atoms, resulting in two resonance structures.

Sorry, it's impossible to draw with a keyboard!
Download and install the WinBGIM Devpack. Once installed, you can include graphics.h to draw graphics.
Structures in C and C++ differ in that C structures do not have an automatic typdef associated with them.

I have a 1989 Browning Accelerator Plus and I was wanting to adjust the draw length?
Put their names into the parameter-list.
As far as C++ is concerned files do not have structures, they are simply raw data streams. It's entirely down to the programmer to determine what structures exist within the file and to interpret the data accordingly. C++ cannot do it for you.
