Answer:

Abrasion

Explanation:

Here's an example, strong winds on a beach where some rocks are cause the sand to rub against the rocks, causing heat and eventually crack and destroy the rock. The ice of glaciers can also break down rocks when rocks are frozen inside it, and that's cooling.

J. Explain how an atom's valence electron configuration determines its place on the periodic table.​
Darya [45]

Answer:

Elements having same valence electrons are placed in <u>same group.</u>

Explanation:

First, let's start with some basic concepts of modern periodic table:

1. Modern Periodic table : It is the arrangement of element in the increasing order of their atomic numbers

The Modern periodic table is divided into Periods and groups .

Periods : These are the horizontal rows. There are seven periods in the periodic table . Period 1 has 2 element. Period two and three has 8 elements , period 4 and 5 have 18 elements and the period 6 and 7 have 32 elements.

Same period have same number of atomic orbital(Shell)

Group : The group is the vertical columns . There are 18 groups in the modern periodic table.Those element which have same group number will also have same number of electron in their outermost shell. The number of electron in the outermost shell determines the valency of the element.

So, elements showing same valency are placed in same group.

All alkali are place in group 1 and have 1 valance electron in the outermost shell

What is true about elements that are in the same column group or family
shusha [124]

The given question is incomplete. The complete question is:

Which is true of Elements on a periodic table in the same group (family)?

A; Elements in the same family have similar chemical properties because they have the same number of electron shells.

B; Elements in the same family have similar chemical properties because they have the same number of valence electrons.

C; Elements in the same family have few similar properties as they have different numbers of electron shells.

D; Elements in the same family are always the same type of Elements and have the same number of protons.

Answer: B; Elements in the same family have similar chemical properties because they have the same number of valence electrons.

Explanation:

Elements are distributed in groups and periods in a periodic table.

Elements that belong to same groups will show similar chemical properties because they have same number of valence electrons. The chemical reactivity of elements is governed by the valence electrons present in the element.

Example: Flourine, chlorine and bromine are elements which belong to Group 17. They have 9, 17 and 35 electrons respectively and contain 7 valence electrons each and need one electron to complete their octet.

Which statement describes the bonds in iron sulfate, FeSO4?
Feliz [49]

___

Regarding the bonds in FesO₄, Fe and S have an ionic bond, while S and O have covalent bonds.

Elements form bonds to increase their stability. The main types of bonds are:

  • Metallic bonds: they are formed between metals and the electrons are in a delocalized cloud.
  • Ionic bonds: they are formed between metals (lose electrons) and nonmetals (gain electrons)
  • Covalent bonds: they are formed between nonmetals, which share electrons.

Regarding the bonds in FesO₄:

  • Fe is a metal and S a nonmetal, thus they will form ionic bonds.
  • S and O are both nonmetals, thus they will form covalent bonds.

Regarding the bonds in FesO₄, Fe and S have an ionic bond, while S and O have covalent bonds.
