I think it's atom but...This is a little confusing..

Answer 1

An atom, letter B.



An element is a broader term that describes a certain type of atom. A collection of identical atoms can be called an element. this is a categorical word.



A compound is a combination of different elements.



A metal is a specific category of elements generally referring to those on the left-side of the periodic table.



An atom is the most unique term and cannot be subdivided

Answer 2

The atom is a basic unit of matter that consists of a dense, central nucleus surrounded by a cloud of negatively charged electrons. The atomic nucleus contains a mix of positively charged protons and electrically neutral neutrons (except in the case of hydrogen-1, which is the only stable nuclide with no neutrons). The electrons of an atom are bound to the nucleus by the electromagnetic force. Likewise, a group of atoms can remain bound to each other, forming a molecule. An atom containing an equal number of protons and electrons is electrically neutral, otherwise it has a positive or negative charge and is an ion. An atom is classified according to the number of protons and neutrons in its nucleus: the number of protons determines the chemical element, and the number of neutrons determines the isotope of the element.[1]

Answer 3

B.atom

The chemical bonds holding all of the others together can be broken.

You can also tell because whenever they talk about "building blocks of all matter" it is usually talking about atoms.

Answer 4

although I've read some other answers here where people believe the answer is "element", the best answer is indeed "atom"

Answer 5

If the answer is A or B the question should have 'an' before the blank.

If it is 'a' the answer can be either C or D.

The question has grammatical error.

Answer 6

True
