In this paper, we introduce and study $w_1$-elements in a commutative ring with unity $R$. An element $0 \neq x \in R$ is said to be a $w_1$-element of $R$ if whenever $xd = x$ for $1 \neq d \in R,$ then there exists $0 \neq z \in R$ such that $dz = 0$. We show that if $Ann_R (x) = Ann_R (y)$ then $x$ is a $w_1$-element of $R$ if and only if $y$ is a $w_1$-element of $R,$ that every $w_1$-element of $R$ is also a $w_1$-element of its polynomial ring $R[x]$ and that if $x^2$ is a $w_1$-element of $R$ with $J=Ann_R(x),$ then $x+J$ is a $w_1$-element of its quotient ring $R/J$.
