Which one of the atoms shown would be most likely to form an anion with a charge of 1?

For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge.

Which of the following statements correctly describes any chemical reaction that has reached equilibrium group of answer choices?

Which of the following statements correctly describes any chemical reaction that has reached equilibrium? … Both forward and reverse reactions have halted.

How does an atom form an anion quizlet?

How do anions form? The gain of negatively charged electrons by a neutral atom produces an anion.

Which of the following has negligible mass?

electron
An electron is a negatively charged particle that travels in the space around the nucleus. In other words, it resides outside of the nucleus. It has a negligible mass and has a charge of –1.

Which of the following statement is true about chemical reactions?

In a chemical reaction formation of new products take place and mass is conserved in a chemical reaction as the mass of the reactants before the reaction is equal to the mass of the products after reaction. Therefore, option D is correct.

Which of the following correctly describes all chemical equilibrium?

Which of the following correctly describes chemical equilibrium? Forward and reverse reactions continue with no effect on the concentrations of the reactants and products. What is the maximum number of hydrogen atoms that can be covalently bonded in a molecule containing two carbon atoms?

Which subatomic particle has a negligible mass?

electron
Neutrons have no charge. With regard to mass, protons and neutrons are very similar, and have a much greater mass than electrons. Compared with neutrons and protons, the mass of an electron is usually negligible.

Which particle has mass but not charge?

neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It has no electric charge and a rest mass equal to 1.67493 × 10−27 kg—marginally greater than that of the proton but nearly 1,839 times greater than that of the electron.

Do electrons have negligible mass compared to the mass of a neutron?

Electrons are extremely small. The mass of an electron is only about 1/2000 the mass of a proton or neutron, so electrons contribute virtually nothing to the total mass of an atom. Electrons have an electric charge of −1, which is equal but opposite to the charge of a proton, which is +1.

Which subatomic particle has the least mass?

the electron
Of the three subatomic particles, the electron has the smallest mass. The mass of an electron is 1/1840 of an atomic mass unit (amu).

Do subatomic particles have mass?

Masses for the three subatomic particles can be expressed in amu (atomic mass units) or grams. For simplicity, we will use the amu unit for the three subatomics. Both neutrons and protons are assigned as having masses of 1 amu each. In contrast, the electron has a negligible mass of .

Which subatomic particles makes up most of the mass of the atom?

The majority of an atoms’ mass comes from the protons and neutrons that make up its nucleus. Electrons are the least massive of an atom’s constituent particles, with a mass of 9.11 x 10–31 kg and a size too small to be measured by current techniques.

Which particle has the least mass proton or neutron?

Since the mass of an electron is so small in comparison to the mass of a proton and neutron, we ignore this number when making this calculation. The majority of the mass of the atom is found in the nucleus, which is made up of protons and neutrons. The part of the atom with the smallest mass is the electron.

Which particle has the greatest mass?

neutron
The subatomic particle with the largest mass is the neutron. However, the difference in mass between a neutron and proton is very small.

Which particle has a mass that is approximately equal to the mass of a proton?

neutron
neutron: A subatomic particle forming part of the nucleus of an atom. It has no charge. It is equal in mass to a proton or it weighs 1 amu.

How do you know which particle has the lightest mass?

electron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10−31 kg, which is only 1/1,836the mass of a proton.

Which particle has the least mass Alpha or Beta?

Comparing only the three common types of ionizing radiation, alpha particles have the greatest mass. Alpha particles have approximately four times the mass of a proton or neutron and approximately 8,000 times the mass of a beta particle.

What particles have approximately the same mass?

Atomic particles

Protons and neutrons have approximately the same mass. However, one proton is about 1,835 times more massive than an electron. Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well.
