Where Is The Divide? The Divide is a common term for a ...
Some atoms don”t have any protons. … Protons and neutrons have charges of the same magnitude but opposite signs.
Which of the following statements about the masses of subatomic particles is true? Protons, neutrons, and electrons all have about the same mass. Electrons have very little mass compared to protons and neutrons. Electrons have no mass.
Whereas ionic reactions are shown by only ionic compounds that is, compounds which are fromed by transfer of electrons between two atoms. Hence, we can conclude that the statement which is not true about covalent compounds is that they show ionic reactions.
The statement that is TRUE about atoms is “electrons determine the size of the atom.” The electrons surround the nucleus of an atom and they determine the space in which an atom occupies.
Option A is false. Atoms are not able to exist independently. All the elements on the far right side of the periodic table (inert or noble gas) atoms can exist independently because they all fulfil the octet rule. … If electrons are lost or gained by a neutral atom, a charged particle is formed called as an ion.
Answer: (a) An atom has equal number of electrons and protons. An atom is electrically neutral because the number of protons is always equal to a number of electrons. Hence option (a) is right.
The answer is the option (ii) neutral. p-Type semiconductors have no charge and are neutral. They conduct electricity through positive holes.
The Correct Answer is Only A is true. An ion is an atom or a group of atoms that does not equal the number of electrons to the number of protons. Electrons have a negative charge, whereas there is a positive charge for protons.
When an atom loses or gains electrons its forms its corresponding ion, and hence it differs in number of electrons. For example, H atom has 1 electron. Whereas H+ ion has 0 electrons.
How are atoms and elements related? An atom is the basic unit of life, and an element is one type of atom, or a group of the same type of atoms. All atoms of the same element have the same number of protons. Atoms of different elements differ in the number of protons.
Atoms themselves are composed of protons, neutrons, and electrons. Each element has its own atomic number, which is equal to the number of protons in its nucleus. Isotopes of an element contain different numbers of neutrons. Elements are represented by an atomic symbol.
No atoms are destroyed or created. The bottom line is: Matter cycles through the universe in many different forms. In any physical or chemical change, matter doesn’t appear or disappear. Atoms created in the stars (a very, very long time ago) make up every living and nonliving thing on Earth—even you.
[Explanation] Idea a: All matter is made up of particles called atoms and molecules (as opposed to being continuous or just including particles).
