Chemistry questions and answers. The protons and neutrons make up the nucleus of the atom which is surrounded by the electrons belonging to the atom. The atom consists of a small positively charged nucleus at its centre and surrounded by negatively charged electrons in a definite circular path.
Electrons are arranged around the nucleus in the shells of an atom. In simple terms an atom is a cloud of tiny electrons buzzing round a central much larger nucleus in a series of orbits called shells. Structure of diatomaceous earth damages and dehydrates the bodies of many insects and many soil pests.
An atom maybe described as the smallest particle that matter is made with and has the properties of a chemical element. The shells of an atom are numbered 12 3 and so on starting from the one closest to the nucleus. Which of the following best describes the structure of an atom.
The mass number of an atom is found by adding together the number of protons and neutrons. It described the overall structure of the atom how atoms bond to each other and predicted the. How is the structure of an atom best described.
And finally the charge of an atom is determined by the. A neutral core surrounded by mostly empty space C. The Electronic Structure of an Atom.
Electrons in orbit about a nucleus of protons and neutrons. Neutral atoms have equal numbers of protons and electrons. A positive core surrounded by mostly empty space D.
Neutrons in orbit about a nucleus of protons bound to electrons. Electrons in orbit about a nucleus of protons and neutrons. Each of these parts has an associated charge.
A neutral atom is BEST described as having. We have one lone pair thus the bond angles are less than 90 0 and 180 0 Because of repulsions between the lone-pair electrons and the IF bonding pairs the plane of the four F atoms at the base is raised slightly above the I atom remember lone pair needs more room. Electrons and neutrons in orbit about a nucleus of protons 3.
The number of electrons will determine how atoms interact with one another and decide if the atom as a whole is positive negative or neutral. A 250-cm-long cylindrical glass tube sealed at one end is filled with ethanol. Atoms consist of three basic particles.
What are atoms made of. A neutral nucleus circled by particles with positive and negative charges. The nucleus contains all the protons and neutrons of the atom.
Neutrons in orbit about a nucleus of protons bound to electrons. The nucleus is small and dense compared with the electrons which are the lightest charged particles in nature. The density of ethanol is 0789 gmL.
