Explanation:
When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral. ... Chemically, we say that the atoms have formed bonds.
Answer:
B or A
Explanation:
choose wether A or B... give it a higher level of thinking. and good luck!
Molecular Formula: H5O5V-5
23.22%:
2.5 L in mL : 2.5 * 1000 = 2500 mL
23.22 g ----------- 100 mL
? g ------------- 2500 mL
m = 2500 * 23.22 / 100
m = 58050 / 100
m = 580,5 g
Answer: (3) silicon
Explanation:
Element is a pure substance which is composed of atoms of similar elements.It can not be decomposed into simpler constituents using chemical reactions.Example: Silicon (Si)
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: ethane
, propanone
and water
