Answer:
d. Metallic
c. S
Explanation:
A metallic bond is an interatomic bond in which valence electrons are constantly moving between atoms like a sea of electrons.
- The formation of this bond type is favored by a large atomic radius, low ionization energy, and a large number of electrons in the valence shell.
- The metallic bond is an attraction between the positive nuclei of all the closely packed atoms in the lattice and the electron cloud jointly formed by all the atoms losing their outermost shell electrons.
2. The bond type described in the second problem is an ionic bond. This results in the formation of crystal lattice with strong bonds.
- It occurs between metals and non-metals
- Since Nickel is a metal, sulfur is the only given non-metal that will make it form an ionic bond.
Answer:
(C) Energy is released when the electron is ejected from the atom.
Explanation:
In the Bohr model of the atom, electrons are arranged in energy levels. The electrons in the lowest energy levels are nearest to the nucleus. An electron may move from a lower to a higher energy level by absorbing energy that is equal to the difference between the energies of the higher and lower energy level.
The potential energy of all electrons inside the atom have negative values and an electron which is infinitely far from the nucleus has an electrostatic potential energy of zero.
Energy is absorbed when an electron is removed from the atom (ionization). Hence the process is highly endothermic. Therefore it is false to say that "Energy is released when the electron is ejected from the atom."
Vegetative propagation is a form of asexual reproduction of a plant. Only one plant is involved and the offspring is the result of one parent. The new plant is genetically identical to the parent. i hope this helped <3
