Questão 3
Questão
In the periodic table, metals are best described as located
Responda
-
on the left side
-
on the right side
-
in the first two rows
-
in the last two rows
Questão 4

Responda
-
1A
-
2A
-
7A
-
8A
Questão 5
Questão
The electronegativity of an element indicates the relative ability of its atoms to attract electrons in a chemical bond. According to the graph, as you move across a period on the periodic table, the atomic number
Responda
-
increases and the electonegativity increases
-
increases and the electonegativity decreases
-
decreases and the electonegativity increases
-
decreases and the electonegativity decreases
Questão 6
Questão
The ionization energy of an element indicates the energy it takes to remove an electron from the outermost level. As you move down a group in the periodic table, the ionization energy
Responda
-
decreases because the electron is farther from the nucleus
-
increases because the number of protons increases
-
decreases because the number of neutrons increases
-
increases because of the size of the atom increases
Questão 7
Questão
How many electrons does the element found in the second row and second column of the periodic table have available for bonding?
Responda
-
0
-
1
-
2
-
4
Questão 8
Questão
Why are the elements in column 17 of the periodic table have in the outer shell?
Responda
-
They have only one electron in their outer electron shells, so they frequently form singly charged positive ions
-
They have only two electrons in their outer shells, so they frequently bond with doubly charged negative ions.
-
They need only two electrons to complete their outer shells, so they easily bond with doubly charged positive ions.
-
They need only one electrons to complete their outer shells, so they easily bond with many types of elements
Questão 9
Questão
Which part of the atom has the least amount of mass?
Responda
-
first s orbital
-
neutrons
-
nucleus
-
protons
