The atom is the smallest particle that uniquely defines an element like a fingerprint C. Atoms of most elements cannot exist independently although inert gases can exist as atoms. None of the above.

Which of the following statement s isare not true regarding a covalent bond. A predicts that world production of conventional crude will soon peak b is based on the fact that oil is a finite resource c has yet to be shown to be true for a single nation d predicts a production decline to follow a decline in new discoveries. None of the choices b.

Which of the following statements are true regarding a covalent bond between nitrogen and hydrogen atoms in an ammonia NH3 molecule. Energy is released when a covalent bond is formed. Inert gas The elements in Group 18 of the periodic table are known as noble gases.

A Yes because oxygen is in the air we breathe and it doesnt hurt us. The electrons are completely transferred from one atom to another. Every atom does not have net electrical charge thus the number of electrons and protons are equal in number.

1 pointThe molecule is composed of four atomsThe molecule contains oxygen atomsThe molecule is waterThe molecule represents an element. Option B is true. The Composition of Atoms Quick Check questions and answers Science 8 A Unit 3.

According to Daltons atomic theory all matter is made of atoms and atoms are indivisible and not destructible. Electrons have very little mass compared to protons and neutrons. D Yes because the Octet Rule says stable atoms have 8 electrons.

The bond formed may or may not be polar. Atoms are only about 10 -10 m across B. Which statement is true about the following molecule.

These elements are also known as the inert gases. Which of the following statements about the masses of subatomic particles is true. C No because the atoms have only 6 valence electrons but need 8 for stability.

The reactivity of an atom is based on the number of electrons in its outer valance shell. Yes isotopes of an element have the same number of proton. All of the above three answers are correct E.

In the industry advantage is often taken of the differences in atomic mass of isotopes to separate them so they can be separated by physical means. So the statement -Daltons theory recognized that all matter is composed of atoms- is true whereas the statement - Daltons theory recognized the existence of smaller particles within atoms is false. Protons and neutrons have very little mass compared to electrons- wrong Electrons have no mass.

Which of the following statement is true regarding atoms. Isotopes of an element truly have same chemical properties due to same number of valence electrons. An _____ is made up.

Are these atoms stable and why or why not. Both protons and neutrons reside inside the atoms nucleus. The bond length is less than the sum.

Check all that apply. The atoms may be of the same type of element or they may be different. In the covalent bond each atom contributes an equal number of electron s.
