Explanation:

Which description best explains a molecular bonding? Shares electrons

A covalent bond is also known also known as molecular bonding because sharing of electrons occur between two or more atoms.

  • Molecular bonds are formed between two or more atoms having zero or very small electronegativity difference between them.
  • This bond type exists between molecules of non-metals.
  • Each of the atom tends to share the valence electrons in their outer energy levels to be able to mimic the noble gas structure.
  • This bond type results in formation of molecules.

Isotopes of the same elements always have the same Z-number

Isotopes of an element have the same electronic configuration hence they have the same chemical properties.

  • isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers.
  • This is due to the differences in the number of neutrons in their various nuclei.

  A- number is the mass number or atomic mass number of an atom.

  Z-number is the atomic number of an atom

Isotopes have the same atomic number.

Some of the heavy particles bounced off the foil, because there is a dense, positive area in the atom.

  • Rutherford performed an experiment that gave that atomic model a significant leap.
  • He found out most alpha particles passed through the foil while a few of them deflected back.
  • He proposed that an atom is made up of a small positively charge center where nearly all the mass is concentrated.

Burning paper

  • A chemical change is one in which a new kind of matter is formed.
  • Chemical changes are always accompanied by energy changes which can be absorption or evolution.
  • These processes are not easily reversible.
  • It involves a change in mass
  • It requires considerable amount of energy.

When a paper is burnt, it turns to ashes. Ashes cannot be turned back into a paper. This is a chemical change.

######

It remains the same

When the number of neutrons in an atom increases, the atomic number stays the same.

  • The atomic number is the number of protons in an atom.
  • Protons are positively charged particles in the nucleus of an atom.
  • When the number of neutrons changes, the mass number changes.
  • Neutrons have no effect on the number of protons in an atom.
  • They are both sub-atomic particles with electrons

######

Equal number of protons and electrons

Protons are the positively charged particles in atom. Electrons are the negatively charged particles in an atom.

  • Every atom is electrically neutral.
  • Electrical neutrality is achieved when the number of protons and electrons are the same.
  • In atoms, this number is the same.
  • If the number differs, such an atom is called an ion.

11 electrons

In a neutral atom, the number of protons and electrons are the same.

  • Protons are the positively charged particles in an atom.
  • Electrons are the negatively charged particles in an atom.
  • Neutrons do not carry any charges in an atom.
  • A charged atom is an atom that has lost or gained electrons.
  • In a neutral atom, the number of protons and electrons are the same.

Thomson            D) Electrons

Rutherford          B) Nucleus

Bohr                    C) Electron energy levels

Schrodinger       A) Electron cloud and orbitals

  • J.J Thomson experimented on gas discharge tubes and this led to the discovery of electrons as a subatomic particle. He called the particles cathode rays.
  • Ernest Rutherford performed the gold foil experiment that gave the modelling of the atom a significant boost. He found that most of the alpha particles passed through the foil while a few of them deflected back. To explain this, he suggested that an atom is made up of a positively charged center where nearly all the mass is concentrated.
  • Neil Bohr suggested that the extranuclear space is made up of electrons in specific spherical orbits. Electrons move round the nucleus in certain permissible orbits called energy levels.
  • Erwin Schrodinger formulated the wave equation for electrons. He suggested that the region of maximum probability of where n electron is located is referred to as an electron cloud or orbital.

Nitella [24]

Answer:

hydrogen bridge

Explanation:

Joule's relationship to heat and temperature is true for all materials where we assume that interatomic forces are linear, when atoms separate these forces decrease. There is a point where the separation between atoms is enough that thermal agitation can separate the molecules and there is a change of state, generally from solid to liquid and from liquid to vapor. When these changes of state are occurring all the energy supplied is used to break the links, so the temperature does not change.

In the specific case of water, there is a bond called a hydrogen bridge that breaks around 4ºC, therefore, at this temperature there is a deviation from the curve since this link is being broken, this does not lead to a change of macroscopic state.

For the other temperatures the water behaves like the other bodies.

Paraphin [41]

Answer:

1.3636

Explanation:

Write the expression for the refractive index.

n=c/v

c= speed of light in air

v= speed of light in material

=(3×10^8 m/s)/(2.2×10^8 m/s)

 =1.3636

NeX [460]

Answer:

(a). The average speed is 51.83 m/s.

(b). The average velocity over one revolution is zero.

Explanation:

Given that,

Angular velocity = 110 rev/m

Radius = 4.50 m

(a). We need to calculate the average speed

Using formula of average speed

v=r\omega

v = 4.50\times110\times\dfrac{2\pi}{60}

v=51.83\ m/s

(b). The average velocity over one revolution is zero because the net displacement is zero in one revolution.

Hence, (a). The average speed is 51.83 m/s.

(b). The average velocity over one revolution is zero.
