What else can I help you with?
What is true about elements in each groups?
They have the same number of valence electrons and so have similar reactivity and similar properties.
What causes the atomic size to increase within the groups of the periodic table?
The atomic size increases within a group in the periodic table due to the addition of energy levels as you move down the group. As you go down a group, each element has one more energy level than the one above it, leading to an increase in atomic size.
What is the definition of equal groups in math?
The definition of equal groups are having the same number of units in each group. An example is how would someone put 15 items in 3 equal groups. Each group would have 5 items.
How does reactivity correlate to each elements location on the periodic table?
Reactivity is associated with position. Chemical properties of element can be determined from its position.
How could you change an experiment to be able to put all six metals into order of reactivate?
To put all six metals in order of reactivity, you can immerse each metal strip in a series of different metal salt solutions with increasing reactivity. Then observe and record the reactions at each stage to determine the relative reactivity of each metal. By comparing the results, you can establish the order of reactivity for all six metals.
What elemental trend exists in each row as we move from left to right on the periodic table Number of protons decreases Number of protons increases Chemical reactivity of metals increases Chemical rea?
As we move from left to right across a row on the periodic table, the number of protons increases. This increase in protons leads to a greater positive charge in the nucleus, which attracts electrons more strongly, resulting in a decrease in atomic size. Additionally, the chemical reactivity of metals generally decreases, while the reactivity of nonmetals tends to increase.
How does the reactivity of each group of metals change across the table from the right?
Reactivity of metals decreases from left to right in the specific period of theperiodic table.
What each vertical column in the periodic table knows as?
Each vertical column in the periodic table is known as a group or family. Groups have similar chemical properties due to their same number of valence electrons, which influences their reactivity and bonding behavior. Elements in the same group often form similar types of compounds.
How does the reactivity of each group of metals change across the table left to right?
Reactivity of metals decreases from left to right in the specific period of theperiodic table.
How does the reactivity of each group of metals change across the table from right to left?
Reactivity of metals decreases from left to right in the specific period of theperiodic table.
How does the reactivity of each group of metal of change across the table from left to right?
Reactivity of metals decreases from left to right in the specific period of theperiodic table.
What are unique chemical groups confer special properties to an organic molecule called?
Unique chemical groups that confer special properties to an organic molecule are called functional groups. These groups determine how the molecule interacts with other substances, influencing its reactivity, solubility, and overall behavior in chemical reactions. Examples of functional groups include hydroxyl (-OH), carboxyl (-COOH), and amino (-NH2) groups. Each functional group imparts specific characteristics that are crucial for the molecule's role in biological systems.
