Answer:

Yes

Bones sustain our bodies, and help shape our form. While very thin, the bones are large enough to bear all of our mass. Bones shield the organs of the body too. The skull supports the brain, and creates the face shape.

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.

How does an atom of one element differ from the atom of another element?
Temka [501]

Explanation:

The atoms of one element differs from the atoms of other elements in terms of the number of protons they contain. This is often taken as the atomic number of such an atom.

  • The number of proton is the best indicator of the atom one is dealing with.
  • Based on this number, elements are categorized into distinct columns and rows on the periodic table.
  • The atomic number is the number of protons or positively charge particles in the atom.

II.

It is possible to change the identity of an atom. This is only possible by altering the atomic number of the atom.

Only nuclear reactions have this capability.

When an atom undergoes nuclear reaction that involves change in number of protons, transmutation occurs and a new atom forms.
