Describe the structure of atoms
Electrons, neutrons, and protons are the three particles of bits which are answerable for
charge and mass of atoms. The nucleus is the region of the atom, which is in the center of atom
comprising protons, which is positively charging and neutrons, which is charge free. The outside
area of a particle named electron shells which holds negatively charged electrons in the nucleus
orbit. Particles have several possessions based on the number and arrangement of their essential
bits and retain all chemical characteristics of an element.
Explain how atoms are charged
That defines a particle with a neutral charge is one where the number of the electrons is
similar to the atomic number. Ions consist of are atoms with some missing or extra electrons. In
the time positively charged particles hit atoms in the nuclear chamber, they cause some electrons
in bits to be knocking away. When more than one electrons are caught another bit, then the
particles are charging positively. It is known as a positive ion. But the negative ion is made by
the measurement of an atomic electron. Subsequently, there are more positive charges than
negative charges. The atom has a positive charge. The consequence of adding the charges of both
positive and negative particles are named as the net charge. When one electron is detaching from
neutral Na atom, there are 10 electrons and 11 protons.
Identify different types of atoms
Most frequently, these atoms are in equilibrium, and as like the bit is constant and lasts
strictly forever. Individual atoms are out of balance (Bernath 2015). These can create them
radioactive. Atoms in a chemical component that have several numbers of neutrons than

UNIT 7 ANSWER
2
electrons and protons are named isotopes. The atoms in a specific element have an
undistinguishable number of protons and electrons but can have changing the neutrons number.
Radioactive:
Individual atoms have several neutrons in the nucleus, making them unbalanced.
Poisonous for providing off particles until stable.
Isotopes:
Every single atom is a chemical component like chorine, hydrogen, iron. Each element
has isotopes; they have several numbers of neutrons. Extra neutrons create isotope as a
radioactive element.
Antimatter:
Each atomic atom has a twin antiparticle with a differing electric charge. Antimatter
hydrogen atoms have designed in the lab containing anti-electron and anti-neutron. Antimatter is
the contradictory of normal matter (Bernath 2015). More exactly, the sub-atomic atoms of
antimatter have possessions opposite those of standard matter.
Ions:
Atoms with the missing or extra electron are ions. Negative or positive electric charge.
Answerable for many chemical reactions.
Describe molecular biological structures
Structure of lipids

UNIT 7 ANSWER
3
All lipids comprise one hydrocarbon chain, which is a chain of hydrogen or carbon atoms
with an acidic end. Lipids have extended hydrocarbon chains which is the reason don’t dissolve
in water. Fatty acids are a describing feature of fats, they are a long hydrocarbon chain with the
acidic head with a chemical structure –COOH (Mohun et al. 2014). Lipid, any of a different
group of organic compounds counting oils, fats, hormones, and particular components of
membranes that are gathering together because they do not interrelate significantly with water.
Steroids:
Steroids are a specific type of lipid. They are categorized by having carbon atoms
prepared into four adjacent rings. The three rings made from 6 carbon atoms and the ending ring
prepared from 5 carbon atoms. A number of damaging and unhealthy effects may affects from
the use of anabolic steroids that can lead to both physical and emotional problems. Studies have
revealed that misuse of steroids can increase destructive behaviour, cause impair judgment or
mood swings.
Phospholipids:
A phosphate group has a charge negatively, and other molecules can link themselves to
the phosphate group. The fatty acids are unsolvable in water. It contains TWO type fatty acids
attached to the three glycerol molecules (Palanca et al. 2014). These are soluble in water and is
therefore involved in water (hydrophilic). The phosphate collections face towards outwards the
water-based settings of the cell. A phospholipid membrane covers two layers of phospholipids.
This phospholipid bilayer obstructs materials moving in the outer compartment.
