They all have the same number of core electrons
What do all elements in one row in the periodic table have in common?
they all have the same number of core electrons
Are the atoms the same or different in hydrogen?
All hydrogen atoms are the same but they are different from the atoms of other elements.
What is the common between all the elements in the same column in the periodic table?
Elements that are contained within the same column in the periodic table are known as a group. All of the elements in the first group of the table have one electron in their outer shell.
What do all the same elements have in a group in common?
Same elements of group have same valency. They possess same chemical behaviour.
What are elements in the same?
All elements in the same horizontal row of the Periodic Table are in the same period, there are 7 periods.
All compounds are formed of what?
all compounds are formed of one or more elements..
What do all elements in a group have on a periodic table?
All elements in a group have same chemical properties. They have same number of valence electrons.
Where are elements with the same number of valence electrons?
Elements with the same number of valence electrons are found in the same group or column of the periodic table. This is because elements in the same group have the same number of valence electrons, which determines their chemical properties. For example, all elements in group 1 have 1 valence electron.
State two characteristics shared by elements of the same group in the periodic table?
They are all composed of the same elementary particles, i.e. all of them have protons and electrons (and all but one have neutrons). Also: - all of them have mass - all of them exist in space and time - all of them interact with other elements by means of electromagnetic forces and gravitational forces - all of them exist in more than one isotopic variety.
How many elements contain the same number of outer electrons as sodium?
Elements in the same group as sodium (Group 1) all contain the same number of outer electrons, which is one. Therefore, there are six elements in the same group as sodium: lithium, potassium, rubidium, cesium, francium, and hydrogen.
What does the group of A elements tell about valence electrons?
All elements in the same A group will have the same number of valence electrons.
