The elements in period 3 and above have d orbitals available for bonding which makes the "expansion" of the octet more likely. period 2 elements do not, the 2d shell has only s and p orbitals.
P is in period 3, an example is PCl5 with 5 electron pairs. Se in period 4 can also expand its octet, an example is SeF6, with 6 electron pairs.
No, lipids are not capable of causing molecules to change. The items that actually cause them to change are enzymes.
Both are capable in hydrogen bonding and protolysis (proton, H+, exchange)
No, hydrogen bonds are not formed between benzene molecules.
Yes the oxygen is capable of bonding with two other molecules because of its 2- charge and two hydrogens have a 1+ charge each.
When the surface of a piece of chalk is scrapped the tiny particles that flake off are known as. A. Matter B. Molecules C. Elements D. Atoms…….. The flakes are particles of whatever the chalk is made of (calcium sulphate or carbonate plus a binding agent)…I needn’t remind you that atoms and molecules are not visible to the naked eyes...If the chalk is white, the flakes falling off are also white. Again atoms have no colors. Although molecules have characteristic colors, they can’t be seen with unaided eyes.. Now let’s assume the chalk is made up of a single compound let’s say Calcium sulphate (made up of Calcium, Sulphur and Oxygen elements)..individually and independently the smallest bit of a compound capable of independent existence is a molecule, the molecules in turn are made up of atoms of elements CHEMICALLY BOND TOGETHER. One cannot separate the atoms just by scrapping the chalk as they are again Chemically bonded. Notice how I used the word ATOMS for ELEMENTS and MOLECULES for COMPOUND. Meaning an ATOM is the smallest unit of matter that retains all the chemical properties of an ELEMENT and Molecule the smallest unit of a compound capable of independent existence, retaining all properties of that compound or Simply a group of atoms chemically bounded together…Again, the flakes settle on standing which suggests that they are actually PARTICLES, not ATOMS, not MOLECULES not ELEMENTS. PARTICLES is the most appropriate ANSWER to the above question..
These are nonmetals.
Atoms of most elements are not able to exist independently. Atoms form molecules or ions aggregate in large numbers to form the matter that we can see. Molecule is capable of independent existence.

passive elements
Yes they are.
Elements are made up of atoms while compounds are made up of molecules. When the atoms of at least two different elements chemically combine, they form molecules and those molecules make up a compound. All elements are capable of combination with other elements to form thousands of different compounds that have completely different characteristics than their elemental parents. A common example is Sodium (Na), (a very reactive metal that reacts violently with water), and Chlorine (Cl), (a poisonous gas) When these elements are chemically combined, they form a completely new substance, harmless table salt (NaCl), a compound.

ATOMS;in the simplest way we can define an atom as the building blocks of all the matter in the universe.atoms are very small that cannot be compared to anything else MOLECULES;a molecule is the smallest particle of an element or a compound that is capable of an independent existence and shows all the properties of that substanceELEMENTS;elements are the basic form of a matter that cannot be broken down into simpler substances by chemical reaction,Elements are normally divided int metals nonmetals and metalloids.COMPOUNDS;A compound is a substance composed of two or more elements,chemically combined with one another in a fixed proportion.
