Answer: The ionization energies of anions of group 17 elements will be higher than for neutral atoms of the same group.

Explanation:

The ionization energy is the energy required to remove an electron from the valence shell of an isolated gaseous atom of an element.

Ionization energy depends on:

a) Electronic configuration of an element: If on losing or gaining of an electron an element attains noble gas configuration or half filled stability then it will be difficult to remove the electron from stable configuration.

b) size of an element :larger the size more lesser the effective nuclear charge on electron thus lower the ionization energy.

Group 17 elements have 7 valence electrons and thus on gaining one electron , they attain stable noble gas configuration and thus the ionization energy will become higher.

What is emitted when an electron returns to its lower energy level?
Yakvenalex [24]

Answer:

When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.

Pb has an atomic number of 82. It has an isotope Pb-207. The mass number is 207.
nikdorinn [45]

Answer:

Number of protons = 82

Explanation:

Given data:

Atomic number of Pb = 82

Mass number of Pb-207 = 207

Number of protons = ?

Solution:

An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.

All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.

Atomic number of Pb = number of protons or electrons

82 = number of protons or electrons

Mass number = Number of protons + number of neutron

207 = 82 + number of neutron

Number of neutrons = 207 - 82

Number of neutrons = 125
