Which two terms relate and why? Compound, ion, proton
Lerok [7]

ion, proton

Explanation:

Ions and protons have profound relationships.

An ion is an atom that has lost or gained electrons.

A proton is a positively charged subatomic particle.

What is the relationship between an ion and a proton?

  • In an atom, there are three fundamental particles.
  • Protons are the positively charged particles located in the nucleus of atoms.
  • Electrons are the negatively charged particles orbiting round an atom.
  • Neutrons have no charges and they occupy the nucleus with protons.

Atoms are electrically neutral and this implies that they have equal number of protons and electrons.

In an ion, the number of protons and electrons differ.

For positive charged ions, the number of protons is more suggesting they have lost electrons.

For negatively charged ions. the number of protons is less suggesting they must have added electrons.

Compound are combinations of different atoms.

Whic number of the periodic table is the atomic number and which number is the atomic mass?
Anettt [7]

Answer:

The mass number (represented by the letter A) is defined as the total number of protons and neutrons in an atom. Consider the element helium. Its atomic number is 2, so it has two protons in its nucleus.

The atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu. By definition, an atom of carbon with six neutrons, carbon-12, has an atomic mass of 12 amu.

A light twig is barely floating on the surface of water. What will most likely happen to the twig if a drop of dishwashing deter
ankoles [38]
It will sink below the surface. Since dish soap is a surfactant, it will alter the water's surface tension. Lowering the surface tension, the water will no longer be able to support the mass of the twig.
