negative ions form when atoms _______ valence electrons.
Answers
Answer:
Negatively charged ions are called anions, and an anion is formed when an atom gains an electron. Thus, the atom has an extra charge of electrons,
Explanation:
so it becomes negatively charged.
Negative ions (or anions) are atoms that have gained electrons.
Electrons have a negative charge so if an atom is getting more of them, it's becoming more negative.

how do anion formation and valence electrons relate?
Answers
Answer:
A cation is formed when a metal ion loses a valence electron while an anion is formed when a non-metal gains a valence electron. They both achieve a more stable electronic configuration through this exchange.

Use the diagram to identify each item.
Answers
Explanation:
atomic no. is 42
chemical symbol is Mo
no. of protons is 42
atomic mass is 95.95
no. of electrons is 42
no. of electron in outer most shell is 1
no of electrons in the n 3 shell is 18
no. of neutron is 96
The element molybdenum is 42nd element in periodic table with the symbol Mo and a mass of 96. It have 42 electrons and 42 protons.
What is Molybdenum?Molybdenum (Mo) is a transition metal in periodic table included in the d-block. The atomic number of molybdenum is 42 which is the number of protons and electrons in it.
The atomic number of a neutral atom is equal to the number of electrons in it. For a neutral atom the number of electrons and protons are equal and thus the number of both electrons and protons in Mo is 42.
Mass number is the sum of number protons and neutrons in an atom. The mass number of Mo is 96 and number of protons is 42. Thus, the number of neutrons is 96 -42 = 54.
The outer shells of Mo are 4d and 5s containing 4 and 2 electrons respectively. Thus the number of outer electrons is 6.The level n= 3 is M shell which contains 18 electrons for Mo.

Look at the image shown.
Two H are written with a horizontal straight line between them. (H-H)
What does this image represent?
Linear molecule with one domain
Linear molecule with two domains
Tetrahedral molecule with four domains
Trigonal planar molecule with three domains
Answers
Explanation:
It is known that an electron pair represents a domain. Hybridization of BF_{3}BF3 will be calculated as follows.
Hybridization = \frac{1}{2}[\text{Valence electrons of central atom + no. of bonded atoms + negative charge - positive charge}]21[Valence electrons of central atom + no. of bonded atoms + negative charge - positive charge]
Valence electrons of boron are 3 and no. of bonded atoms in a BF_{3}BF3 molecule is 3.
Therefore, calculate hybridization of BF_{3}BF3 as follows.
Hybridization = \frac{1}{2}[\text{Valence electrons of central atom + no. of bonded atoms + negative charge - positive charge}]21[Valence electrons of central atom + no. of bonded atoms + negative charge - positive charge]
= \frac{1}{2}[3 + 3 + 0]21[3+3+0]
= 3
Hence, hybridization of BF_{3}BF3 is sp^{2}sp2 , that is, trigonal planar.
Thus, we can conclude that the given image represents that it is a trigonal planar molecule with three domains.
Answer:
electron pair => 1 covalent bond => same as H:H
Explanation:
The bar notation is generally accepted as a pair of electrons depicting a 'single' chemical bond. If two bars are shown (e.g; C=C) then two chemical bonds are represented. If three bars are shown (e.g; N≡N) then three chemical bonds are represented. This is the highest number of bonds that can exist between two elements. Hope this helps. :-)

Answers
Answer:
No change...
Explanation:
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.
